	if available). The supported names are \bksh\b, \bbsh\b, \bbash\b, and
	\bosh\b. \bosh\b forces the \bread -r\b compatibility read command to
	be compiled and used instead of \bread -r\b. The default is determined
	by probing the shell at startup.]:[name]
[S:static?Sets the C compiler flags that force static linking. If not set
	then \biffe\b probes the compiler to determine the flags. \biffe\b
	must use static linking (no dlls) because on some systems missing
	library symbols are only detected when referenced at runtime from
	dynamically linked executables.]:[flags]
[u:undef?\b#undef\b failed test macros. By default only successful test macros
	are defined \b1\b.]
[v:verbose?Produce a message line on the standard error for each test as
	it is performed.]
[x:cross?Some tests compile an executable (\ba.out\b) and then run it.
	If the C compiler is a cross compiler and the executable format is
	incompatible with the execution environment then the generated
	executables must be run in a different environment, possibly on
	another host. \acrosstype\a is the HOSTTYPE for generated executables
	(the \bpackage\b(1) command generates a consistent HOSTTYPE namespace).
	Generated executables are run via \bcrossexec\b(1) with \acrosstype\a
	as the first argument. \bcrossexec\b supports remote execution for
	cross-compiled executables. See \bcrossexec\b(1) for
	details.]:[crosstype]
[X:exclude?Removes \b-I\b\adir\a and \b-I\b*/\adir\a C compiler flags.]:[dir]

[ - ] [ file.iffe | statement [ : statement ... ] ]

[+SYNTAX?\biffe\b input consists of a sequence of statement lines. Statements
	that span more than one line contain \abegin\a\b{\b as the last
	operand (where \abegin\a is command specific) and zero
	or more data lines terminated by a line containing
	\b}end\b as the first operand. The statement syntax is:
	[\aname\a \b=\b]] [\b!\b]] \atest\a[,\atest\a...]] [\b-\b]]
	[\aarg\a[,\aarg\a...]]]] [\aprereq\a ...]]
	[\abegin\a{ ... |\bend\b ...]] [= [\adefault\a]]]].
	\atest\as and \aarg\as may be combined, separated by commas, to perform
	a set of tests on a set of arguments. \aname\a \b=\b before \atest\a
	overrides the default test variable and macro name, and \b-\b after
	\atest\a performs the test but does not define the test variable and
	macro values. \b!\b before \atest\a inverts the test sense for \bif\b,
	\belif\b, and \byes{\b and \bno{\b blocks.]
[+?\aprereq\as are used when applying the features tests and may be
	combinations of:]{
		[+compiler options?\b-D\b*, \b-L\b*, etc.]
		[+library references?\b-l\b*, *\b.a\b, etc. \b_LIB_\b\aname\a
			is defined to be 1 if \b-l\b\aname\a is a library.]
		[+header references?*\b.h\b. \a_dir_name\a is defined to be 1
			if \adir/name\a\b.h\b is a header, or if \adir\a is
			omitted, \b_hdr_\b\aname\a is defined to be 1 if
			\aname\a\b.h\b is a header.]
		[+-?Prereq grouping mark; prereqs before the first \b-\b are
			passed to all feature tests. Subsequent groups
			are attempted in left-to-right order until the first
			successful group is found.]
	}
[+?\abegin\a\b{\b ... \b}end\b delimit multiline code blocks that override
	or augment the default code provided by \biffe\b. User supplied code
	blocks should be compatible with the K&R, ANSI, and C++ C language
	dialects for maximal portability. In addition to all macro definitions
	generated by previous tests, all generated code contains the
	following at the top to hide dialect differences:]{
		[+#if defined(__STDC__) || defined(__cplusplus) || defined(c_plusplus)?]
		[+#define _STD_ 1?]
		[+#define _ARG_(x) x?]
		[+#define _VOID_ void?]
		[+#else?]
		[+#define _STD_ 0?]
		[+#define _ARG_(x) ()?]
		[+#define _VOID_ char?]
		[+#endif?]
		[+#if defined(__cplusplus)?]
		[+#define _BEGIN_EXTERNS_ extern "C" {?]
		[+#define _END_EXTERNS_ }?]
		[+#else?]
		[+#define _BEGIN_EXTERNS_?]
		[+#define _END_EXTERNS_?]
		[+#endif?]
		[+#define _NIL_(x) ((x)0)?]
	}
[+?= \adefault\a may be specified for the \bkey\b, \blib\b, \bmac\b, \bmth\b
	and \btyp\b tests. If the test fails for \aarg\a then
	\b#define\b \aarg\a \adefault\a is emitted. \bkey\b accepts multiple
	\b= \b\adefault\a values; the first valid one is used.]
[+?Each test statement generates a portion of a C language header that contains
	macro defintions, comments, and other text corresponding to the feature
	tests. \b#ifndef _def_\b\aname\a\b_\b\adirectory\a ...
	\b#endif\b guards the generated header from multiple \b#include\bs,
	where \aname\a is determined by either the \brun\b statement input file
	name if any, or the first \atest\a in the first statement, and \adirectory\a
	is the basename component of either the \brun\b statement file, if any,
	or the current working directory. The output file name is determined
	in this order:]{
		[+-?If the first command line operand is \b-\b then the output
			is written to the standard output.]
		[+--output=\afile\a?Output is \afile\a.]
		[+set out \afile\a?Output is \afile\a.]
		[+[run]] [\adirectory\a/]]\abase\a[\a.suffix\a]]?Output is
			\bFEATURE/\b\abase\a.]
	}
[+?Generated \biffe\b headers are often referenced in C source as:
	\b#include "FEATURE/\b\afile\a". The \bnmake\b(1) base rules contain
	metarules for generating \bFEATURE/\b\afile\a from
	\bfeatures/\b\afile\a[\asuffix\a]], where \asuffix\a may be omitted,
	\b.c\b, or \b.sh\b (see the \brun\b test below). Because
	\b#include\b prerequisites are automatically detected, \bnmake\b(1)
	ensures that all prerequisite \biffe\b headers are generated before
	compilation. Note that the directories are deliberately named
	\bFEATURE\b and \bfeatures\b to keep case-ignorant file systems
	happy.]
[+?The feature tests are:]{
	[+# \acomment\a?Comment line - ignored.]
	[+cmd \aname\a?Defines \b_cmd_\b\aname\a if \aname\a is an executable
		in one of the standard system directories (\b/bin, /etc,
		/usr/bin, /usr/etc, /usr/ucb\b).
		\b_\b\adirectory\a\b_\b\aname\a is defined for \adirectory\a
		in which \aname\a is found (with \b/\b translated to \b_\b).]

	[+dfn \aname\a?If \aname\a is a macro in the candidate headers then
		a \b#define\b \aname\a \avalue\a statment is output for the

		guarded.]
	[+exp \aname\a \aexpression\a?If \aexpression\a is a \"...\" string
		then \aname\a is defined to be the string, else if the
		\bexpr\b(1) evaluation of \aexpression\a is not 0 then \aname\a
		is defined to be 1, otherwise \aname\a is defined to be 0.
		Identifiers in \aexpression\a may be previously defined names
		from other \biffe\b tests; undefined names evaluate to 0.
		If \aname\a was defined in a previous successful test then
		the current and subsequent \bexp\b test on \aname\a are
		skipped. If \aname\a is \b-\b then the \aexpression\a is
		simply evaluated.]
	[+hdr \aname\a?Defines \b_hdr_\b\aname\a if the header
		\b<\b\aname\a\b.h>\b exists. The \b--config\b macro name is

	[+if \astatement\a ... | \belif\b \astatement\a ... | \belse\b
		| \bendif\b?Nested if-else test control.]
	[+iff \aname\a?The generated header \b#ifndef-#endif\b macro guard is
		\b_\b\aname\a\b_H\b.]
	[+include \afile\a [ re ]]?Read #define macro names from \afile\a
		and arrange for those names to evaluate to 1 in \bexp\b
		expressions. If \are\a is specified then macros not matching
		\are\a are ignored.]
	[+key \aname\a?Defines \b_key_\b\aname\a if \aname\a is a reserved
		word (keyword).]
	[+lcl \aname\a?Generates a \b#include\b statement for the native version
		of the header \b<\b\aname\a\b.h>\b if it exists. Defines
		\b_lcl_\b\aname\a on success. The \b--config\b macro name is
		\bHAVE_\b\aNAME\a\b_H\b. The default \are\a is \b^HAVE_\b
		for \b--config\b and \b^_\b otherwise.]
	[+lib \aname\a?Defines \b_lib_\b\aname\a if \aname\a is an external
		symbol in the default libraries.]
	[+mac \aname\a?Defines \b_mac_\b\aname\a if \aname\a is a macro.]
	[+mem \astruct.member\a?Defines \b_mem_\b\amember\a\b_\b\astruct\a

	[+npt \aname\a?Defines \b_npt_\b\aname\a if the \aname\a symbol
		requires a prototype. The \b--config\b macro name is
		\bHAVE_\aNAME\a\b_DECL\b with the opposite sense.]
	[+num \aname\a?Defines \b_num_\b\aname\a if \aname\a is a numeric
		constant \aenum\a or \amacro\a.]
	[+nxt \aname\a?Defines a string macro \b_nxt_\b\aname\a suitable for
		a \b#include\b statement to include the next (on the include
		path) or native version of the header \b<\b\aname\a\b.h>\b
		if it exists. Also defines the \"...\" form
		\b_nxt_\b\aname\a\b_str\b. The \b--config\b macro name is
		\bHAVE_\b\aNAME\a\b_NEXT\b.]
	[+one \aheader\a ...?Generates a \b#include\b statement for the first
		header found in the \aheader\a list.]
	[+pth \afile\a [ \adir\a ... | { \ag1\a - ... - \agn\a } | < \apkg\a [\aver\a ...]] > ]]?Defines
		\b_pth_\b\afile\a, with embedded \b/\b chars translated to
		\b_\b, to the path of the first instance of \afile\a in the
		\adir\a directories. \b{\b ... \b}\b forms a directory list
		from the cross-product of \b-\b separated directory groups
		\ag1\a ... \agn\a. < ... > forms a directory list for the
		package \apkg\a with optional versions. The \b--config\b macro
		name is \aNAME\a\b_PATH\b.]
	[+run \afile\a?Runs the tests in \afile\a based on the \afile\a
		suffix:]{
		[+.c?\afile\a is compiled and executed and the output is copied

	[+siz \aname\a?Defines \b_siz_\b\aname\a to be \bsizeof\b(\aname\a) if
		\aname\a is a type in any of \b<sys/types.h>, <times.h>,
		<stddef.h>, <stdlib.h>\b. Any \b.\b characters in \aname\a are
		translated to space before testing and are translated to \b_\b
		in the output macro name.]
	[+sym \aname\a?Defines \b_ary_\b\aname\a if \aname\a is an array,
		\b_fun_\b\aname\a if \aname\a is a function pointer,
		\b_ptr_\b\aname\a if \aname\a is a pointer, or

		but does not define a macro.]
	[+(\aexpression\a)?Equivalent to \bexp -\b \aexpression\a.]

	[+cat?The block is copied to the output file.]
	[+compile?The block is compiled (\bcc -c\b).]
	[+cross?The block is executed as a shell script using \bcrossexec\b(1)
		if \b--cross\b is on, or on the local host otherwise, and the
