Hmm. Is that really the best approach unless absolutely necessary? "That

I'm not sure "repaired" is the right word for this
I don't think it is. Gcc-4 is Cygwin 1.7's system compiler, so there's
nothing wrong with (parts of) the ocaml package depending on it.
But I guess the ability to switch the default compiler back to gcc-3
should come with a health warning: it may break stuff. Time to get rid
of the gcc alternatives setup perhaps, and require users to specify
gcc-3 explicitly if they still want it?
I don't believe this is an issue with which compiler is used. The
issue is simply that the OP is trying to build brltty with gcc-3 while
not rebuilding (or using) dependencies (ocaml) built with gcc-3. I'd
wager that just installing the old Cygwin ocaml packages that were
built with gcc-3 would fix the problem, though like I said in my
reply, I didn't actually test that theory. Of course, that's not a
general recipe for success, since older packages built on gcc-3 may
not always be available. So anyone that wants to build with gcc-3
must be prepared to build all dependencies. Like most software, the
compiler is backward-compatible but isn't forward-compatible. But
you're right. In a nutshell, if you don't consider and address these
issues when using gcc-3 to rebuild packages, "it may break stuff". :-)
