Bootstrap comparison failures

[Andrew Stanley]

I've been working on trying to compile GCC 3.1.1 on HP/UX 11.11 (11i) this
afternoon.  I'm consistently getting, after the stage3 bootstrap is
complete,  the following error:

'Bootstrap comparison failure!
alias.o differs
attribs.o differs
...
intl/plural.o differs
intl/textdomain.o differs'

It seems to barf on every single object created.  I initially noticed that
BOOT_CFLAGS and STAGE1_CFLAGS were different (BOOT_CFLAGS was set to -O2).
I modified the makefile and re-made, and I'm still seeing this issue.

I'm using GNU as, and also tried doing a make boostrap4, and I've had no
luck.  Any ideas?

Thanks,

-Andrew
