Debian linux
kernel 2.2.x (- which was 2.0 or 2.2 of debian I think, can't remember)
glibc 2.1.3
gcc 2.95.2
it looks like the thread stuff is enabled in ports/linux in cvs tip

hmmmm...

Make sure you have added any needed 'THREAD_CPPFLAGS' and 'THREAD_LIBS'
defines to your template/$port file before compiling this program.

Your gethostbyname() is _not_ thread-safe
Your getpwuid() is _not_ thread-safe
Not all non-*_r functions are thread-safe.
Add this to your template/$port file:

NEED_REENTRANT_FUNCS=yes
