[Haskell-cafe] HP/Cygwin and Curl

Thanks very much Claus and Malcolm.

You have clarified the situation nicely: I was beginning to suspect my
Cygwin setup and I bet that is where the problem lies.

I won't have time to straighten my Cygwin environment this week, but when I
do I will come back here and explain what went wrong (I have seen evidence
of others stumbling on this giving rise to speculative misinformation).

Sorry for the confusion!

This sounds very much like a temporary-filename issue.  The reported
filename's lack of a valid directory specifier looks highly suspicious to
me.  Are your TEMP, TEMPDIR, TMP, and TMPDIR environment variables set? Are
their values sensible?  Do you have appropriate permissions on the
directories they point to?  These are the kinds of thing I usually need to
check when setting up a new Cygwin build environment.

Admittedly, we do not use cabal on Windows (firewall prevents it from
working), but the other ghc tools generally seem to work without problems
for us under Cygwin.
