I'm using the gnu grep utility (as ported from the latest - version 2.5.2 I
believe). With its -r switch, it has a limited recursive ability. However,
I've found that any filename pattern matching is case sensitive, which in
windows, it should not be. Does anyone know how to override this, or maybe
can point me to a grep that is fully gnu-compatible, with all of its latest
fixes and everything, while also fixing this filename case sensitivity
issue? Any help would be appreciated.

Here is a thread I had started in the gnu.utils.help/bug forum, which
eventually pointed me to windows-related groups.
