right.  i also have macppc i haven't tested.

build.sh -V HAVE_GCC=48.

*that*'s the ABI issue that has had its fix checked in yet, but is
not related to the compiler version.

actually, my pegasos has had a GCC 4.8 userland for about a year,
but only ever had one kernel that booted (i suspect somethings
are just aligned right), until recently i had been GCC 4.5 kernels
only.

i didn't compare them recently, but last time i did, the userland
was identical output with a GCC 4.5 kernels.
