My Cygwin is recent (one week old).
I have the same source tree for gcc, gcc/gmp, gcc/mpc and gcc/mpfr as the one
advised here (4.6.0, 4.3.2, 0.9 and 3.0.1).

Along with Cygwin comes:
- libgmp, libgmp3, libgmpxx4 and libgmp-devel 4.3.1-3
- libmpc1 and libmpc-devel 0.8-1
- libmpfr1 and libmpfr-devel 2.4.1-4
I edited /usr/local/include/gmpxx.h to added "choke me" in order to verify if
it's used by gcc's "make" despite gmp's source being in my source tree.

gcc output is in an "objdir" directory separate from my gcc source directory.
Configure script (after a "make distclean" command in "objdir"), with "objdir"
as my present working directory :
/"path to my source"/configure --enable-cx

then:
make

That's the configuration I'm testing now ("make" isn't finished). The first
build failures I refer too were done with pretty much the same configuration,
but for a trunk version of gcc and a one-two months old Cygwin. As I've lost
track of this precise configuration, I'm trying again with the configuration
described above.

I won't fight on this point, ;-).
If my bug shows up again, I'll submit a specific bug report, so as not to
pollute this one.

Thank you.
