changing "fd_mask" to "fd_set" and re-running worked for me.
I sure hope it doesn't break someone else.

A quick grep of GLIB shows that `gmain.c' and `gerror.c' have typedefs
for `fd_mask', but it isn't used anywhere else.  Will anything break
if 

1. I replace `fd_mask' with `fd_set' in the configure check
2. Remove the `fd_mask' typedefs
