I was this having problem on the NetWinder (armv4l arch) for the longest
time with objc.

I noticed the following files were regenerated during my build:
	egcs/gcc/objc/objc-parse.c
	egcs/gcc/objc/objc-parse.y

diffing these against those in my clean cvs tree I found that objc-parse.c
was generate with bison version 1.27, whereas the clean one was generated
with version 1.25.

Downgrading bison to version 1.25 has allowed me build egcs (latest cvs)
without further complaint.

This may be relevant to others problems, or it may be a problem on my end
with bison on the NetWinder.  Just thought I'd mention it.
