    SpaceCommas	       Use spaces after commas (default on).
    SpaceFuncs	       Use spaces after function names (default off).
    NoBanner	       Suppress "From input file..." comment at top of file.

Version 1.18:

 * Improved indentation strategy for EMBED comments.

 * Allowed one-line EMBED comments: {EMBED foo();}

 * Made {SKIP} ... {NOSKIP} comments nestable.  ({NOSKIP ... } isn't nestable.)

 * Changed to emit comments in export sections of modules in correct order.

 * Rewrote decl.c:p_arraydecl slightly to avoid a gcc bug.

 * Bug fix in expr.c:makeexpr_sizeof: Compute size by hand if SkipIndices used.
   Symptom: Size was "sizeof(arr)" even if it should have omitted skipped part.

 * Bug fix in trans.h: Added #undef _toupper/_tolower at end.
   Symptom: Failed to compile on Apollos.

 * Bug fix in parse.c:fixblock: Added "sp->stm1 &&" check for WHILE statements.
   Symptom: "while cond do ;" caused a reference-to-NULL error.

 * Bug fix in decl.c:makefakestruct: Suppressed fakestruct when importing.
   Symptom: Importing a module generates two declarations for _REC_A.

 * Bug fix in Makefile: Added rules to make home dirs if not found.

Version 1.17:

 * Introduced "StructFile" stuff to help with more intensive file operations.

 * Simplified "N + 0.0" to "(double)N" instead of "N" when appropriate.

 * Fixed typo in sys.p2crc: "LogBreakPenalty" => "RelBreakPenalty".

 * Changed to avoid generating bit fields as members of a union.

 * Now "stringarray[i] := expr" will sprintf expr into lhs with no temp var.

 * Handled assignment of small packed arrays of chars into big ones.

 * Added to sys.p2crc/trans.h the following configuration parameters:

    CharConsts      Assume "const c='x'" is a char, not string constant.
    SelfIncludeName Format to use when a module includes its own .h file.
    StructFiles     Translate files as special structs rather than FILE *'s.
    StructFile      A file variable to be treated as if StructFiles=1.

Version 1.16:

 * Reduced wasteful proliferation of identical-looking temporary variables.

 * Improved heuristic for determining allocation size for set constructors.

 * Corrected handling for EOF applied to buffered binary files.

 * Bug fix in decl.c: Handled a rare case involving forward-declared pointers.

 * Bug fix in p2clib.c:P_setxor: Forgot to fix s[0] if highest bits cancelled.

 * Added to sys.p2crc/trans.h the following configuration parameters:

    EofBufName      Macro to use for EOF of a bufffered file.
    FilePosBufName  Macro to use for FILEPOS or POSITION of a buffered file.

Version 1.15:

 * Taught the line breaker to handle logical/relational operators specially.

 * Improved code generation for large set constructors.

 * Changed makeexpr_assign to handle EK_LITCAST's on the lefthand side.

 * Changed makeexpr_addr to handle casts.

 * Changed FieldMacros so that the substituted base expr retains its type.

 * Bug fix in p2c.h: Rewrote P_getbits_US and other small-packed-array macros.
   Symptom: On many architectures, these macros didn't work at all!
   NOTE: These now pack small arrays in the opposite direction (LSB first).

 * Bug fix in funcs.c:handleread_text: changed strread of string to use %255s.
   Symptom: Previous translation of %255c did not append a null character.

 * Bug fix in p2clib.c:strrtrim: Added test for empty string input.
   Symptom: Incorrect behavior on strrtrim("").

 * Bug fix in p2clib.c:P_addsetr: Changed to signed comparison of v1 and v2.
   Symptom: Adding [0..-1] to a set failed.

 * Bug fix in p2clib.c:P_expset: Don't write to d[1] if set is empty.
   Symptom: Sets allocated to store 0 elements didn't work properly.

 * Added to sys.p2crc/trans.h the following configuration parameters:

    LogBreakPenalty         Like OpBreakPenalty, but for && and ||.
    LogBreakExtraPenalty    Like OpBreakExtraPenalty, but for && and ||.
    RelBreakPenalty         Like OpBreakPenalty, but for <, ==, etc.
    RelBreakExtraPenalty    Like OpBreakExtraPenalty, but for <, ==, etc.

 * Added partial support for Oregon Software Pascal's delete(f) procedure.

 * Changed file_iofunc to be a little more robust in case of errors.

 * Bug fix in p2clib.c:strrtrim: Changed to "while (*++s2) ;"
   Symptom: This function didn't do anything!

 * Bug fix in decl.c:p_type: Declared enums which were base types of sets.
   Symptom: In "type s = set of (a,b)", the enum was never declared.

 * Bug fix in decl.c:issafename: Avoided #defining existing field names.
   Symptom: "type r=record a:integer; end; const a=10;" produced bad code.

 * Bug fix in expr.c:makeexpr_charcast: Changed to recognize CONST names.
   Symptom: "const x='x'; var s : set of char; s := [x];" generated bad code.

Version 1.13:

 * Changed to interpret cpp-style "#include" as another include-file syntax.

 * Improved handling of WRITE field widths for packed arrays of char.

 * Improved handling of built-in identifiers in PascalCaseSens mode.

   Symptom: In PascalCaseSens mode, forward declarations had to be capitalized.

Version 1.12:

 * Added support for Sun/Berkeley Pascal.

 * Beefed up PascalCaseSens handling.

 * Added some extra parentheses to the P_clrbits macros. (!)

 * Added to sys.p2crc/trans.h the following configuration parameters:

    CharFileText    Treat "file of char" as identical to "text".
    UseStrncmp	    Use strncmp, not memcmp, to compare packed arrays of char.
    MessageStderr   Built-in "message(...)" should use stderr, not stdout.
    LiteralFiles    Files opened without names should use file var's name.
    LiteralFile	    Specific files which should use LiteralFiles=1 mode.

Version 1.11:

 * Improved the "usage" message slightly.

 * Introduced "CollectNest=0" to help with include files of sub-procedures.

 * Changed to ignore "OVERLAY" keyword (a Turbo Pascal anachronism).

 * Introduced "BROKEN_OR" option in trans.h in case of compiler bugs.

 * Changed src/Makefile to check for presence of nroff before changing p2c.cat.

 * Taught strmax_func to understand string consts as well as string literals.

 * Prevented variables in varstructs from being declared "const".

 * Changed "checkvarchanged" in decl.c to observe constqual, volatilequal.

 * Introduced "expr_has_address" (in expr.c) as a variant on "expr_is_lvalue".

 * Bug fix in pexpr.c:p_funcarglist: for strings as conformant arrays, low=1.
   Symptom: Strings were passed as array [0..N] instead of [1..N].

 * Bug fix in decl.c:setupmeaning: added missing "break;" for MK_VARIANT case.
   Symptom: Special formatting for enumerated type names was broken.

 * Bug fix in p2c.h:P_getcmdline: removed "Const" keywords.
   Symptom: Prototype was inconsistent with definition in p2clib.c.

 * Bug fix in decl.c:addfield: changed to "tname && tname->name ? ...".
   Symptom: Reference to NULL formatting field names for unnamed records.

 * Bug fix in expr.c:fixblock: fixed getfbuf + get => fread to check var type.
   Symptom: "f:file of byte; i:integer; i:=f^; get(f);" used fread incorrectly.

 * Bug fix in lex.c:turbo_directive: checked return value of handle_include.
   Symptom: Turbo-style include directives messed up if file was not found.

 * Added to sys.p2crc/trans.h the following configuration parameter:

    CollectNest     Kludge to make sub-procs be emitted as they are parsed.

Version 1.10:

 * Bug fix in comment.c:addnote: reference to "quiet" changed to "quietmode".
   Symptom: Failed to compile!  (Sorry, about that!)

Version 1.09:

   Symptom: Dangling pointer problems generating calls to P_read[ln]paoc.

 * Bug fix: in pexpr.c:dots_n_hats:TOK_LBR case: changed to use p_ord_expr().
   Symptom: Arrays indexed by literal characters used "A", not 'A'.

 * Bug fix: in pexpr.c:p_setfactor: added two makeexpr_longcast calls.
   Symptom: Generated code used "1 << x" instead of "1L << x" in a few places.

 * Bug fix: in decl.c:setup_decl: defined SWORD equivalent to tp_sshort.
   Symptom: Signed words were translated as longs under some circumstances.

 * Bug fix: in parse.c:fixblock: "if" rearrangements now clear if-else flags.
   Symptom: Else-ifs were formed in inappropriate places.
