[Bug bootstrap/28994] New: 64-bit problem in host-darwin.c

["lucier at math dot purdue dot edu" <gcc-bugzilla at gcc dot gnu dot org>]

When configuring and bootstrapping with

#!/bin/tcsh
/bin/rm -rf *; env CC='gcc -mcpu=970 -m64' ../configure
--prefix=/pkgs/gcc-test-64 --enable-languages=c --disable-checking; make -j 16
bootstrap BOOT_CFLAGS='-O2 -g -mcpu=970 -m64' >& build.log 

bootstrap fails with

of different size
../../gcc/config/rs6000/host-darwin.c:131: warning: format '%08lx' expects type
'long unsigned int', but argument 3 has type 'unsigned int'

Now, you might say that this isn't the way to try to build a 64-bit compiler
that targets 32-bit binaries, but I still think that there are 32-bit
assumptions in this routine that need to be fixed.
