recent snapshot fail to compile on BSD/OS

recent snapshot fail to compile on BSD/OS

[Shigeya Suzuki]

I've been trying this recently, but everytime I built from CVS
snapshot (I tried several times, including ss-980406) no luck.

I've got coredump on stage1, and stage2. Anything I can help?

This looks like the ASM_OUTPUT_ALIGN problem that {Net,Free,Open}BSD had.
Does this patch (to egcs/gcc/config/i386/bsd386.h) solve your problem?

It works. I try to build with latest snapshot on CVS but I couldn't
build, but snapshot ss-980406 with this patch built without
problem. I'm running check now. 

Thank you!
