What did you mean by "25th december"? Did you mean if I do

# ./contrib/gcc_update -D "Dec 25 00:00 PST 2001"
# apply your fixes.

I can bootstrap on mips? What I got are

# ./contrib/gcc_update -D "Dec 17 09:00 PST 2001"

is ok.

# ./contrib/gcc_update -D "Dec 17 09:30 PST 2001"

is bad.

The only relevant change between them is your patch. You should do

# ./contrib/gcc_update -D "Dec 17 09:30 PST 2001"
# apply your fixes.

and make sure you can bootstrap on mips unless you believe your patch
exposes some latent bugs.
