According to Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>

gcc on IRIX (6.2) does not need and does indeed much better
without -D_POSIX_C_SOURCE [perl #15128] (the inclusion of
_POSIX_C_SOURCE in CFLAGS disables the definition of _SGIAPI
and <sys/dirent.h> doesn't define struct dirent64,
which causes reentr.c not to compile)
