Both are non-standard; if you start adding all the routines that everybody 
wants/needs, then you end up with Win32 API ;-)

beginthreadex is not part of win32 API and has no place in Cygwin runtime.
It's not even part of Windows standard C runtime, but was added later on
to MSVC runtime. If you're going to have MSVC-specific code, then the
correct approach is to write a portability layer to provide emulation 
for other runtimes.

vsnprintf would be a very useful function to have in newlib, but it
doesn't exist there; however, vsprintf/vfprintf/etc do exist and you
should be able to use those instead. Or, get a free version off the net
and add it to your port library.

Regards,
Mumit
