As there localtime_r is also used in intrinsics/date_and_time.c, I would assume
that one sees the same message there.

I am also not quite sure that _REENTRANT is the correct solution. At least for
Solaris, one should use _POSIX_C_SOURCE and not _REENTRANT to get the POSIX
version, cf. http://download.oracle.com/docs/cd/E19455-01/806-5257/compile-4/

For HP-UX, I could not find anything (cf. also
http://docs.hp.com/en/B2355-90683/ctime.3C.html). However, IBM has a statement
regarding HP-UX, which is similar to Solaris's above:
