5b62e6374a compat/regex/regexec.c: Fix some sparse warnings
Sparse issues an "Using plain integer as NULL pointer" warning along
with two "symbol was not declared. Should it be static?" type warnings
for the 'merge_state_with_log' and 'find_recover_state' functions.

In order to suppress the warnings, we replace the use of '0' as a null
pointer constant with NULL and add the static modifier to the function
definitions.

ce518bbd6c Fix compat/regex ANSIfication on MinGW
compat/regexec.c had a weird combination of function declaration in ANSI
style and function definition in K&R style, for example:

 static unsigned
 re_copy_regs (struct re_registers *regs, regmatch_t *pmatch,
      int nregs, int regs_allocated) internal_function;

 static unsigned
 re_copy_regs (regs, pmatch, nregs, regs_allocated)
     struct re_registers *regs;
     regmatch_t *pmatch;
     int nregs, regs_allocated;
 { ... }

with this #define:

 #ifndef _LIBC
 # ifdef __i386__
 #  define internal_function   __attribute ((regparm (3), stdcall))
 # else
 #  define internal_function
 # endif
 #endif

The original version as shown above was fine, but with the ANSIfied
function definition and in the case where internal_function is not empty,
gcc identifies the declaration and definition as different and bails out.

Adding internal_function to the definition doesn't help (it results in
a syntax error); hence, remove it from the subset of declarations that gcc
flags as erroneous.

178b33157a compat/regex: get rid of old-style definition
These files mostly used ANSI style function definitions, but with small
number of old-style ones.  Convert them to consistently use ANSI style.

b50f37098f compat/regex: define out variables only used under RE_ENABLE_I18N
Wrap variables that were only used RE_ENABLE_I18N in `#ifdef
RE_ENABLE_I18N`. This eliminates compiler warnings when compiling with
NO_REGEX=YesPlease.

d18f76dccf compat/regex: use the regex engine from gawk for compat
Change the regex engine in compat to use the gawk engine from the
gawk-devel module in gawk CVS. This engine supports the REG_STARTEND
flag, which was optionally available in Git since v1.7.2-rc0~77^2~1.

The source was grabbed from cvs.savannah.gnu.org:/sources/gawk, and
these are the upstream versions of the files being included:

    regcomp.c               1.4
    regex.h                 1.3
    regex.h                 1.3
    regex_internal.c        1.3
    regex_internal.h        1.3
    regexec.c               1.3
