Joseph's patch doesn't work for me, because the --stack parameter never makes
it to the link line for some reason, and I get the same crash building
cipher.o.  This is the relevant output of bootstrap:

rm -f jc1.exe
/mingw/src/gccf/./prev-gcc/xgcc -B/mingw/src/gccf/./prev-gcc/
-B/mingw/i386-pc-mingw32/bin/  -g -O2 -D__USE_MINGW_ACCESS -DIN_GCC   -W -Wall

../libdecnumber/libdecnumber.a attribs.o -L/mingw/src/gmp-mpfr/root/lib
-L/mingw/src/gmp-mpfr/root/lib -lmpfr -lgmp

I don't know if there is something particular to the way I've configured that
might be making this break for me.  As an additional data point, for some
reason when I tried overriding LDFLAGS previously, the stack parameter also did
not propagate properly to jc1.exe, although it propagated just fine to some of
the other link lines outside of Java.
