Problem in reload.c/rtlanal.c on powerpc-unknown-linux-gnu

[Franz Sirl]

Thanks,

it works, the mainline now bootstraps again with your patch (and without
mine). Testsuite results will follow on egcs@cygnus.com (but ignore the
results from egcs-19981103, they are without the emit-rtl.c fix).

Franz.
