[PATCH] Let gdb know that cygwin is dosish

[Christopher Faylor <cgf@redhat.com>]

I'm not sure if this falls into my jurisdiction or not, but unless
there are objections, I'm going to make the following change.

I recently found that a bug that I'd been halfheartedly tracking
down for months was caused by the fact that some of gdb's code didn't
recognize the fact that f:/ was an absolute path under cygwin.

This patch should fix that as well as a number of other odd
incompatibilities with mixed case.
