Patch: Feature Branch - Windows Build Broken - config.h & relatives

[Conrad T. Pino]

====================
These are best guesses based on brief guidance proved by Derek Price:

> #define inline __inline in windows-NT/config.h.in.in - there should be
> a hook.

Already so defined.

> Add strftime.c to the list of sources compiled for lib on feature.

Done in prior patch that included adding "time_r.c" also.

> #define HAVE_STRFTIME if Windows has a version.

Already so defined.

> #define strftime whatever if Windows has it under another name.

Not required, VC6 provides a definition.

> I don't recall if you need to #define my_strftime to something.  Take
> a cue from other files.

Done as: #define my_strftime strftime
--------------------
VC6 doesn't support C99 "restrict" key word.
--------------------
The consequences of "HAVE_RUN_TZSET_TEST" change aren't totally clear
to me and I'd welcome any feedback.

I did extract and compile the "tzset test" program from "m4/tzset.m4"
and the answer is, "No, tzset does NOT clobber localtime's static
buffer and the wrapper function is NOT required".

#if TIME_WITH_SYS_TIME
# include <sys/time.h>
# include <time.h>
#else
# if HAVE_SYS_TIME_H
#  include <sys/time.h>
# else
#  include <time.h>
# endif
#endif
#include <stdlib.h>
#include <stdio.h>

int
main ()
{
  time_t t1 = 853958121;
  struct tm *p, s;
  putenv ("TZ=GMT0");
  p = localtime (&t1);
  s = *p;
  putenv ("TZ=EST+3EDT+2,M10.1.0/00:00:00,M2.3.0/00:00:00");
  tzset ();
  printf( "%d\n", (p->tm_year != s.tm_year
        || p->tm_mon != s.tm_mon
        || p->tm_mday != s.tm_mday
        || p->tm_hour != s.tm_hour
        || p->tm_min != s.tm_min
        || p->tm_sec != s.tm_sec) );
  return 0;
}
