Subject:	Internal compiler error on compiling windowmaker source with -O6

I was compiling WindowMaker .53 tonight with egcs-pgcc-1.1.1.  When
compiling with -O6, compiliation of one of the .c files, I believe dock.c
informed me that cc1 returned an internal compiler error.  I downgraded by
optimization of the compilation of this file to -O5, and all continued fine.
Thus, it appears to me that this bit of source exploit a bug of the 6th
level optimizations available in pgcc.  Has anyone looked at this, or have
any idea of why this one bit of source caused an internal compiler error at
high optimizations, but not low, while other stuff seem consistent in
compiling or not compiling regardless of optimization levels.
