No, you're getting confused by libiberty.  It is used internally *in*
gcc as a portability aide for gcc itself.  When you call printf in a
Cygwin program, the implementation is in cygwin1.dll, and Cygwin
implements this internally via newlib.  Look at the Cygwin source (which
includes the newlib source) if you want to see how it's implemented, not
the gcc source.
