It's not too hard to determine if gmtime_r needs -D_REENTRANT and then
define GMTIME_R_NEEDS__REENTRANT and then:
#ifdef GMTIME_R_NEEDS__REENTRANT
#define _REENTRANT
#endif
where needed in .c files.
We've done something similar in KDE's configure.ac for HP-UX which
needs _REENTRANT for some functions.
