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.
