That's not a GNU linker error message.  You need to build Cygwin
programs with Cygwin tools.

C library functions are in the in libc.a (aka libcygwin.a) but
you need to be building a cygwin program using Cygwin's gcc for
things to work properly.  You can't just link in a library which
contains fork into a Windows program.  That won't work.
