bootstrap on 3.1 (probably 3.0.4) on i586-pc-sco3.2v5.0.2 --with-gnu-as

[rbrown64@csc.com.au]

Sorry, I should have reported this earlier (& actually tested 3.0.4 rather
than 3.0.3).
Building on i586-pc-sco3.2v5.0.2 --with-gnu-as fails as follows

The -mcoff is provided by

gcc/config/i386/t-sco5gas:CRTSTUFF_T_CFLAGS_S = -mcoff
-fno-omit-frame-pointer

I worked around it by editting the gcc/Makefile. The obvious fix is to
remove the -mcoff from
t-sco5gas .Will try tomorrow when this bootstrap completes.

Robert, do you agree with removing -mcoff from t-sco5gas and is it
sufficiently low impact
to go into 3.0.4?

I went to --with-gnu-as (binutils 2.11) after
