Well, on cygwin you don't really use "libc.a".  You use libcygwin.a 
(which is actually an import lib for cygwin1.dll -- but it is 
cygwin1.dll that contains the "libc" functions, really)

It's not surprising that the glibc stuff doesn't work -- cygwin uses 
newlib's implementations.  (Also, as has been previously stated, newlib 
cannot accept code 'lifted' from glibc for legal reasons).

Right.  If you want 'em, you're gonna have to write 'em from scratch. 
Without borrowing from glibc.  (And then send in a patch to the newlib 
folks.)

Wasn't this just discussed about two days ago?
