Trying to use gas in building gcc-20010115

[James Overly]

Hi -

I am attempting to build gcc-20010115 distribution
on the alpha using OSF 4.0f. I ended up getting an error 
in stage 3 of the bootstrap and it was suggested that
I use gas instead of the native assembler.

When I switch to gas I get the error message:

as: unrecognized option `-O0'
*** Exit 1
Stop.

whenever I try to compile anything. 

It looks like I do not have things setup correctly however 
I can not find anything addressing this in the documentation.
I know I must be doing something stupid.

Any help would be greatly apprecated.

Thanks

Jim Overly
