Ok, with these 2 patches cvs-egcs bootstraps fine again on a glibc-2.0.108
machine with gas-990107 (I wish there was anonymous cvs for binutils/gas too).
I haven't run the testsuite yet, cause this machine is so _slow_
(PPC601/75), I'll let it run today.
Jeff, your initial email suggested that you had problems bootstrapping even
with a recent gas-snapshot. Did you use non-standard BOOT_CFLAGS for that?
