ctime_r call in Solaris 10 SPARC

[florenz@…]

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.

Fixed in 6.4 branch and HEAD.
