	Only include kernel headers if we want thread-safe operation
	Required for PR 17229

Wed Oct 14 17:24:46 1998  Jonathan Larmour  <[e-mail]>

	* include/pkgconf/libm.h: 
	Make CYGPKG_LIBM_COMPATIBILITY_DEFAULT require CYGPKG_LIBC
	rather than all of libm, and put a check (with #error) that
	this is the case

	* src/double/ieee754-api/w_scalb.c:
	Only include errno.h if we aren't IEEE-only

	* src/double/portable-api/s_ldexp.c, src/misc/standard.c:
	Make the error checking in s_ldexp.c more like every other libm
	sources by putting the actual error handling into standard.c.
	The error handling is just like scalb

	* tests/vectors/acos.c, tests/vectors/asin.c,
	  tests/vectors/atan.c, tests/vectors/atan2.c,
 	  tests/vectors/ceil.c, tests/vectors/cos.c, tests/vectors/cosh.c,
 	  tests/vectors/exp.c, tests/vectors/fabs.c,
 	  tests/vectors/floor.c, tests/vectors/fmod.c,
 	  tests/vectors/frexp.c, tests/vectors/ldexp.c,
 	  tests/vectors/log.c, tests/vectors/log10.c,
 	  tests/vectors/modf.c, tests/vectors/pow.c, tests/vectors/sin.c,
 	  tests/vectors/sinh.c, tests/vectors/sqrt.c, tests/vectors/tan.c,
 	  tests/vectors/tanh.c:
	Remove unnecessary include of <errno.h>

	* tests/vectors/vector_support.h:
	Only include errno.h if we aren't IEEE-only.
	If we don't have Cyg_ErrNo, just use a cyg_int32 instead, to
	make sure that the fields are still correct for the input
	test vector.
	In doTestVec(), before checking errno, check if we're
	in IEEE mode (either compiled in or set at runtime) because if
	so, and errno is set in the errno field of the input test
	vector, then we have to skip this, since we can't validate the
	output.
	In all modes, if errno is set in the input test vector, don't
	bother checking the actual values

	All of the above changes are for PR 17503
	
	* tests/vectors/pow.c:
	Remove requirement of being in POSIX mode, as the change to
	vector_support.h should make this work better now.


Sun Sep 27 20:46:09 1998  David Moore  <[e-mail]>

	* include/pkgconf/libm.h:
	PR 17515: Corrected notcdl doc string.

1998-09-26  Bart Veer  <[e-mail]>

	* include/pkgconf/libm.h:
	PR 17503: there are uses of errno in a couple of places in libm,
	and errno will only be available if the C library is present.
	Therefore libm requires libc.
	

Fri Sep 25 19:00:35 1998  Jonathan Larmour  <[e-mail]>

	* src/misc/compatmode.cxx: 
	Make sure CYGNUM_LIBM_COMPATMODE_TRACE_LEVEL is defined before
	we attempt tracing, otherwise set trace level to 0 i.e. never

	* src/misc/signgam.cxx: 
	Make sure CYGNUM_LIBM_SIGNGAM_TRACE_LEVEL is defined before
	we attempt tracing, otherwise set trace level to 0 i.e. never
	Fix for PR 17478

	* include/pkgconf/libm.h: 
	Define trace levels only if parent CYGPKG_LIBM_TRACE is defined
	for consistency with Configuration Tool

Fri Sep 25 18:25:02 1998  Jonathan Larmour  <[e-mail]>

	* include/pkgconf/libm.h: 
	Only check valid compatibility setting if we aren't IEEE-only
	mode
	Fix for PR 17481

Fri Sep 25 18:13:24 1998  Jonathan Larmour  <[e-mail]>

	* src/mathincl/fdlibm.h: 
	* src/double/ieee754-core/e_scalb.c: 
	* src/double/ieee754-api/w_scalb.c: 
	Use CYGFUN_LIBM_SVID3_scalb for whether 2nd arg of scalb is
	double or int, rather than _SCALB_INT.
	Fix for PR 17479

Wed Sep 23 08:07:48 1998  Jonathan Larmour  <[e-mail]>

	* tests/vectors/pow.c (test): 
	Make pow test conditional on being in POSIX compatibility mode.
	This is the only mode that can set errno correctly, in
	relation to what the tests expect.
	Fix for PR 16933

1998-09-20  Mark Galassi  <[e-mail]>

	* include/pkgconf/libm.h: updated CDL doc strings.

Thu Sep 17 17:10:47 1998  Jonathan Larmour  <[e-mail]>

	* tests/vectors/vector_support.h (checkErrorAcceptable): 
	Move check for signed-ness after all of the special cases
	Fix for PR 16933

Tue Sep 15 19:26:32 1998  Jonathan Larmour  <[e-mail]>

	* include/pkgconf/libm.h: 
	Updated descriptions and a few other minor things after review

1998-09-11  Bart Veer  <[e-mail]>

	* include/pkgconf/libm.h:
	Sorting out dependencies for error package.

Fri Sep  4 14:20:04 1998  Jonathan Larmour  <[e-mail]>

	* include/pkgconf/libm.h: 
	Fix thread-safe modes "requires" lines not to be associated
	with the dummy parent package, but with the options themselves.
	Also we don't need "requires CYGPKG_KERNEL" if we already require
	a particular kernel option anyway.

Thu Sep  3 09:50:20 1998  Tim Goodwin  <[e-mail]>

	* tests/vectors/vector_support.h
	Change to cyg_thread_create() interface.

Wed Sep  2 14:41:54 1998  Jonathan Larmour  <[e-mail]>

	* include/pkgconf/libm.h: 
	Add default define for CYGPKG_LIBM_COMPATIBILITY_DEFAULT,
	and shorten some display texts

Wed Sep  2 13:15:43 1998  Jonathan Larmour  <[e-mail]>

	* src/double/ieee754-core/e_pow.c: 
	Fix bug for when x is negative and y isn't an integer. A CYGNUS
	LOCAL change got it wrong when casting a signed integer to
	unsigned before right shifting.
	
	Reformat for 76 columns

	* src/double/ieee754-api/w_pow.c: 
	Reformat for 76 columns

	* include/pkgconf/libm.h: 
	Require infra tracing support to allow tracing

1998-08-28  Bart Veer  <[e-mail]>

	* include/pkgconf/libm.h:
	* src/misc/compatmode.cxx, src/misc/signgam.cxx:
	* tests/vectors/vector_support.h

	Updated for new kernel configuration option symbol names

Fri Aug 28 09:07:07 1998  Jonathan Larmour  <[e-mail]>

	* tests/vectors/vector_support.h:

	cyg_package_start() to get tests working correctly with new entry
	point mechanism, including cyg_iso_c_start() if available

Wed Aug 26 20:25:36 1998  Jonathan Larmour  <[e-mail]>

	<pkgconf/system.h> after all

Tue Aug 25 16:59:11 1998  Jonathan Larmour  <[e-mail]>

	* include/pkgconf/libm.h: 
	Turns out the nesting wasn't quite right. Correct it, and replace
	the "not" prefix on CFG_DATA, which slipped in to the previous change.

Tue Aug 25 16:53:03 1998  Jonathan Larmour  <[e-mail]>

	* include/pkgconf/libm.h: 
	Ensure there is a default compatibility mode and fix the
