At this point, I'd recommend to perform a cygwin update; with Cygwin,
these problems often go away with an update.

If that doesn't help, you can ask on the Cygwin list also; to analyse
this further, ISTM one will need to debug the internals of cygwin.

One thing you could try is to add -v to the list of gcc options;
you can then see whether gcc is progressing correctly.
