The same error occurs on hppa2.0w-hp-hpux11.11.  Adding -pthread to CFLAGS
will provide the define but that will also cause linking against libpthread.

The linux manpage advises not using the nonstandard unlocked variants:

CONFORMING TO
       The     four     functions     getc_unlocked(),     getchar_unlocked(),
       putc_unlocked(),  putchar_unlocked()  are  in POSIX.1.  The nonstandard
       *_unlocked() variants occur on a few Unix systems, and are available in
       recent glibc.  They should probably not be used.
