I guessed a bit backwards and the macro priorities.  For _beginthread to
be declared both __STRICT_ANSI__ and _POSIX_SOURCE must be undefined.
Best I can tell this logic is specific to our gcc/kLIBC ports.  The use of
_WITH_UNDERSCORE and __USE_EMX also appear to be specific to our gcc/kLIBC
ports.  __STRICT_ANSI__ is known to gcc and _POSIX_SOURCE is known to the
POSIX standard. _POSIX_SOURCE appears to be deprecated in favor of

One possible solution is to turn off the -ansi option which may allow
_beginthread to be defined without negative side effects.
