libgcc.a contains a few small routines used by gcc-compiled code
(gcc inserts implicit calls to routines in libgcc.a),
whereas libc.a is the standard C library
(which is called explicitly rather than implicitly).
In b19, libc.a is part of cygwinb19.dll / libcygwin.a,
whereas libgcc.a is not.

If you want to use cygwin*.dll, then you should link with -lgcc and -lcygwin,
not with -lc.
