> 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.
GCC 4.x (in contrast to 3.x) requires GMP, MPFR (and since 4.5 IIRC also
MPC), so these packages should have been pulled in by Cygwin if/when you
installed the GCC4 package.
But didn't you say "GCC3" was the default?
