Comment:
Wooo, I think we have to get back on this one and think a little more.
Indeed I spotted that the cephes spkg failed to install (although that was
not detected properly...).
So we have to check two things:
- why the cephes spkg fails (if it succeeds, it will provide libmc and
libmd),
- if the cephes spkg is really needed, indeed as I mentioned before, I
think that the libm provided by Cygwin is now C99 compliant (enough) and
cephes is not needed anymore (and I don't think keeping it in case one
wants to build Sage on a very old Cygwin with a poor libm is any kind of
justification).
So I think we should first:
- fix the cephes spkg.
Check it is not needed on Cygwin anymore, and if so:
- disable its installation on Cygwin,
- removed all Cygwin specific code involving libmc and libmd.
