There are other platforms where compiling for thread support changes more than 
just adding a library.  For example, in NetBSD 5.0, it looks like stdio.h 
defines getc() in a non-thread-safe way if _REENTRANT and _PTHREADS (which get 
defined by "gcc -pthread") are not defined.  So even with gcc, just replacing 
"-pthread" with "-lpthread" isn't good enough.
