Problem with new option handling?

[Geert Bosch]

During a bootstrap of current mainline on powerpc-apple-darwin6.6, I
get the following messages:
> stage1/xgcc -Bstage1/ -B/usr/local/powerpc-apple-darwin6.6/bin/ -c 
> -mdynamic-no-pic      -gnatpg -gnata -I- -I. -Iada 
> -I/Users/bosch/gcc/gcc/ada /Users/bosch/gcc/gcc/ada/ada.ads -o 
> ada/ada.o
> gnat1: warning: `-gnatpg': unknown or unsupported -g option
> gnat1: warning: `-gnata': unknown or unsupported -g option
> gnat1: warning: `-gnatO': unknown or unsupported -g option

This looks like fallout of the new option handling. Neil, do you
have an idea what's going wrong here? Thanks in advance.
