[PATCH] libgpg-error: Fix windows build

[Andre Heinecke]

Hi,

libgpg-error fails to compile for windows without optimization because it uses 
the FD_ISSET macro and does not link against ws2_32.

Attached patch provides a simple replacement function for FD_ISSET to be used 
on Windows.

Please apply this or fix it in another way, code should not rely on 
optimization behavior to compile.

To reproduce the build error:

../configure --host=i686-w64-mingw32 CFLAGS=
make

Regards,
Andre
