   I believe this is no longer true since we started using `long long'
   for HOST_WIDE_INT for such cross compilers.

In fact it isn't true as far back as when one used to be
able to say "-DHOST_WIDE_INT='long long'" in CFLAGS during
the build.  And I know I was doing that at least 4 years ago
for sparc32-->sparc64 crosses :-)
