That's not really a fix, considering that this is not done by the default
gcc configuration procedure....

If this is `normal procedure', then gcc should default to a 64-bit native
integer type, where available, when targeting a 64-bit target.  Defaulting
to 32-bit HOST_WIDE_INT when it's _known_ [by Cygnus/Redhat] to break is
bogus.
