Like GetCurrentProcess, GetCurrentThread is actually a Carbon function:

http://developer.apple.com/documentation/Carbon/Reference/Process_Manager/Reference/reference.html#//apple_ref/c/func/GetCurrentProcess
http://developer.apple.com/documentation/Carbon/Reference/Thread_Manager/Reference/reference.html#//apple_ref/c/func/GetCurrentThread

The proof by induction about why GetCurrentThread could fail as well,
is left as an exercise for the reader :-)

As suggested by bug #77324 (2006-03-10 16:38), you could try to
reference the Mono framework before Carbon:

	gcc  foo.c -framework Mono -framework Carbon -o ...
