Hi Matt/Camm.

Apart from the patch you mentioned below, I'm not aware of any other similar
bugs being found or fixed since then.  Having said that, I wouldn't have
remembered fixing that bug if you hadn't pointed it out!

Unfortunately the experimental ANSI package is still there as I write, but
the traditional build I just uploaded should be up soon:

I'll discuss this separately just on the GCL developers list.

I'm unclear about what is going on, but if Jared is using a GCL from our
standard installer distribution, then the correct C compiler is included
with that and should operate automagically in GCL without interference from
the surrounding Cygwin tools. (This is different to using GCL directly from
within the source tree.)

I guess you really mean "due to the bug fixed by the following patch".  Yes,
that sounds right, so hopefully an up-to-date GCL will help.

Best of luck to you Jared.  Please let us know how you go with GCL 2.5.3
when it turns up on the download site.
