The Cygwin folks have an issue that GCC-4.6.3 doesn't compile ECL
properly due to a GCC bug

Since this problem doesn't seem to occur with GCC-4.7.2, I would propose
to upgrade Sage's GCC to version 4.7.2. There already exists an optional
package for this, so basically we just need to make that optional
package standard. Several of the buildbots are already using GCC-4.7.x
or even GCC-4.8-trunk, so GCC-4.7.x should be well-tested by now and I
don't expect problems. If nobody complains, I will do this upgrade to
GCC-4.7.2.
Just noticed there are still subtle issues with GCC 4.7.x on Solaris
(due to its math headers).
Singular 3-1-5.p4 doesn't yet build because of these; I'll see whether
there are more instances (i.e., spkgs) later...
(We already fixed FLINTQS and eclib which had the same problem.)
