#775: ctime_r call in Solaris 10 SPARC

GHC 6.4.2 does not build on Solaris 10 because ctime_r takes three instead
 of two arguments.

 The error is in file ghc/rts/RtsUtils.c. I did a quickfix to continue
 building but it is not very nice:

 {{{
 $ diff patched/ghc/rts/RtsUtils.c orig/ghc/rts/RtsUtils.c
 190c190
 <       ctime_r(&now, nowstr, 26);
 ---
 >       ctime_r(&now, nowstr);
 }}}

 An extract of

 $ man ctime

 shows

 {{{
 SYNOPSIS
      #include <time.h>

      char *ctime(const time_t *clock);

      struct tm *localtime(const time_t *clock);

      struct tm *gmtime(const time_t *clock);

      char *asctime(const struct tm *tm);

      extern time_t timezone, altzone;
      extern int daylight;
      extern char *tzname[2];

      void tzset(void);

      char *ctime_r(const time_t *clock, char *buf, int buflen);

      struct tm *localtime_r(const time_t *restrict clock,  struct
      tm *restrict res);

      struct tm *gmtime_r(const time_t *restrict clock, struct  tm
      *restrict res);

      char *asctime_r(const struct tm *restrict tm, char *restrict
      buf, int buflen);
 }}}

 The exact OS version is

 $ uname -a

 SunOS bruja 5.10 Generic_118833-03 sun4u sparc SUNW,Sun-Fire

 My suspect is that something in the autoconf spec is not correct for
 Solaris 10.

 Florian
