Folks,

I am compiling a gcc-2.7.0 cross-compiler, host sun-sparc-solaris2.4,
target decstation-ultrix.  I don't actually need DEC header files or
even libgcc*, as we're using this only with "nachos".  I just need
that compiler.

I'm compiling with gcc-2.7.0 and binutils-2.6.  binutils was
compiled to provied the needed DEC cross linking and assembly.

Here's the offending bit in the compile:

I don't have -O2 specified in the Makefile, I have -O.  I trussed
this; xgcc calls cpp calls cc1 calls as.  Somehow cc1 is the 
offender, changng the -O to -O2 when it calls as.

I read in ChangeLog.2 that gcc.c was modified so that cc1 would
pass on any -O* to as.  Could the problem be in there somewhere?

Or hey can I skip the libraries and just compile and install
gcc?

Thanks for your help!
