I had posted previously about stripping executables on the Mac, with
some confused ramblings about 'astrip' and 'strip'.  Turns out that
'strip' is the one I want, 'astrip' is for use with ACK .o files.

The problem with 'strip' is in a file a.out.h - there are some #defines
which are apparently flipped around from what they ought to be.
I have not yet figured out why this matters, as in strip.c they seem
to always be used in pairs.  But here is the patch, courtesy of Matthias
Pfaller.  After installing this patch and recompiling, strip works fine.
Note my version was compiled with c68, not ACK.

Status: OR

I think your /usr/include/a.out.h is the pc-version. strip compiled on a
68000-system with an pc-a.out.h will behave as you have reported.
The following is a diff between the pc-version and the st-version.
	Hope that helps - Matthias
