RE: bash pwd returning windows style paths

Looking through some of the Eclipse code this looks tricky. I think Eclipse
(the CDT plugin actually) sets it up as a default environment variable so
that any tool it runs can use it (which includes programs not run via bash
and other non-cygwin based tools). If it were removed, I presume other tools
could break that depend on it. Similarly I guess Windows or Ming based tools
would fail if it was a Cygwin path.

Thanks - I tried adding this to the newlib configure script and it now
works.

Fair enough, I guess this probably isn't the right place anyway, as it
wouldn't help other Cygwin programs not run via bash.

I notice that Cygwin does convert the path style for some environment
variables, such as PATH, HOME and TMP. Would it make any sense to add PWD to
that list?

Cheers,
Jon
