Please check the GNU-Win32 sites listed below for further details about Cygwin.
Cygwin has a fully functional self-hosting toolchain. The Cygwin environment implements a functional POSIX layer under Windows. Building GPC for Cygwin should (if you have the full Cygwin environment and toolchain) be as straightforward as building it under Linux.
However, in order to get
a full GPC runtime library, you also need
to download os-hacks.h
copy it to your Cygwin installation's
"include" directory (typically /usr/include/) before
to "configure" and "build" GPC.
