Ulrich Drepper, who is in charge of glibc, is always interested in
following Single Unix to the letter; getc_unlocked is supported
atleast since glibc 2.0.

http://www.sun.com/smcc/solaris-migration/docs/courses/threadsHTML/adv.html

claims that getc_unlocked is already in POSIX.1c; Solaris apparently
supports it atleast since Solaris 2.4.

Irix has it since 6.5, Tru64 atleast since 4.0d (probably much
longer); HPUX since 11.0, AIX since atleast 4.3.

Of the BSDs, only OpenBSD appears to support it; it knows that it is
in ANSI 1003.1 since 1996-07-12.

SCO OpenServer doesn't support it.
