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.

Don't know what the official Cygwin guidelines are, but you may say its
the default because it what the "gcc" package points to.
If you want GCC 4.x (which ships 4.5.x currently), you have to choose the
"gcc4" packages (moreprecisely the "gcc4-core" one if you want the C
compiler, and it should indeed pull mpfr and mpc automagically unless you
prevent setup.exe from doing it, see a list of package I had installed and
with which I got a mostly working Sage install at
