* time/mktime.c: (my_mktime_localtime_r):
Remove. All uses changed to __localtime_r. (__localtime_r) [!defined _LIBC]: New macro. Include "time_r.h" to get its implementation. Fix compile-command to allow for TIME_R_POSIX. * time/strftime.c (my_strftime_gmtime_r, my_strftime_localtime_r): Remove. All uses changed to __localtime_r and __gmtime_r. (__gmtime_r, __localtime_r) [!HAVE_TM_GMTOFF]: New macros. Include "time_r.h" to get their implementations. * time/timegm.c: Allow use in GNU applications outside glibc. [defined HAVE_CONFIG_H]: Include <config.h>. [!defined _LIBC]: Include "timegm.h", <time_r.h>. Define __gmtime_r, and declare __mktime_internal. (timegm): Define via a prototype, since we can safely assume C89 now.
