Thanks, Tom

I'm currently doing battle with cross compilation and dependency
issues. I've downloaded the recommended gmp and mpfr, but
the build is dying because I've installed these to non-standard
locations and can't for the life if me figure out the proper incantation
to get gcc to pick these up. What's more, I'm running into a
cross compilation issue where configure in libstdc++ tries to
run an executable built with the cross compiler. I think I'm going
to give up for today and pick this up later on.

I thought I figured out the dependency issue for ecj branch:

export GMPINC="-I$GMP_MPFR_DIR/include"
export GMPLIBS="-L$GMP_MPFR_DIR/lib -lgmp -mpfr"

$GCC_SRC_DIR/configure --prefix="$PREFIX" \
    --with-sysroot="$SYSROOT" --with-build-sysroot="$SYSROOT" \
    --target=$TARGET --host=$HOST --build=$BUILD \
    --enable-languages=c,c++,java \
    --with-gnu-as --with-gnu-ld \
    --with-mpfr=$GMP_MPFR_DIR \
    --with-gmp=$GMP_MPFR_DIR \
    --disable-nls --disable-debug --disable-shared --disable-checking \
    --enable-threads=win32 --enable-sjlj-exceptions --disable-win32-registry  \
    --enable-libgcj --disable-java-awt --without-x

Things seemed to work until the "let's try to run a Win32 executable
on FC5" stint that libstdc++ configury tried to pull. I then tried pulling
down the trunk to see if the libstdc++ configury fared any better and
am getting the same problem of the build not respecting my non-standard
gmp and mpfr locations....

It's a many-splendored thing....
