It's ANSI C; you can decide whether or not your machine is outdated :-)
My POSIX manual sez:
Conversion: This function is new in Standard ("ANSI") C. It is
not included in BSD or System V prior to SVR4
Notes: This function is required by Standard C. It is not part of
the POSIX standard.
So, Sun just barely squeeks by with POSIX compliance, but not ANSI. It's not too hard to roll-your-own strtoul, though...
