> Weirdly, I just tried a brand-new Cygwin install with the minimal
prereqs that JP has been talking about, and got a very strange error about
cygmpfr-4.dll cannot open shared object file (as well as that I didn't
have Gnu cc and that cc couldn't make executables. Installing the mpfr-4
package from Cygwin seems to have allowed compilation to begin, but that
mpfr came with a SLEW of other packages I didn't really want. In this
case, it seems that even our gcc package would not have compiled, since
Sage thought that the gcc4 on Cygwin was defective somehow.

Strange, Ive always used the gcc4 package (more precisely, the latest
version available for gcc4-core) and got no problems either with that
package only to builg Sage's GCC 4.6.3 or 4.7.2, or together with the
corresponding gcc4-g++ and gcc4-gfortran to builg Sage directly.
I think I never ever tried the gcc3 packages.
I've nevere (intentionally) installed gmp, mpfr not mpc neither.
I'll put my hand on a XP box and will give it a shot.
That may be in a week or two only though.
> Assuming this behaves properly over the next 48 hours or so, I'll yet
again uninstall Cygwin and see what happens with a new one. That said, IF
we can build gcc-4.7 with the gcc3 that is preinstalled on Cygwin, maybe
that would be a reason for the 4.7 standard version.
