FYI: HPPA egcs 20000228 requires new gas => binutils

Tue Feb 29 13:59:00 GMT 2000

Bootstrapping egcs-20000228 using GNU assembler 990824 failed
due to the new SOM weak symbol support.

Bootstrapping using GNU assembler 000228 failed the comparison
- because the code generated by the assemblers differs, having changed
assemblers in mid-build. I assume the differences are PA2.0 instructions.
Should 000228 objdump --disassemble give a clearer distinction between
the forms?
