Re: Patch to make trunk compile on m68k-next-nextstep3 with 3 = 3.2

And also on mine ;-)  Really, the system that I have is a strange  
hybrid, but possibly quite widespread because of NeXT's pricing  
strategy:  The kernel and User Programs are 3.3, but the Development  
Programs (cc, as, ld, gdb, etc) are 3.2:

% cc -v
Reading specs from /lib/m68k/specs
NeXT Computer, Inc. version cc-216.obj~13, gcc version 2.2.2
% as -v
NeXT Computer, Inc. version cctools-28.obj~39, GNU assembler version 1.38
% gdb

It failed because the above mentioned `as' can't handle `.section';  
from my September 20 message on the egcs list:

In the mean time (snapshot CVS'd at 199809201100UTC) I ran into a  
new problem:

../../egcs/gcc/libgcc2.c: In function `in_reg_window':
../../egcs/gcc/libgcc2.c:3527: warning: unused parameter `reg'
../../egcs/gcc/libgcc2.c:3527: warning: unused parameter `udata'
/usr/tmp/ccbbsZ0U.s:987:Unknown pseudo-op: .section
/usr/tmp/ccbbsZ0U.s:987:Rest of line ignored. 1st junk character  
valued 95 (_).

Note that I, personally, do not particularly pine for loosing C++  
capabilities; however, some other users of this 3.2/3.3 hybrid

Thanks for pointing this out, but I'm not hanging onto NEXTSTEP out  
of desperation, but simply because I'm waiting for quad-21264's  
running Linux to become affordable :-)

You bet - the mainline binutils doesn't know a thing about the  
Mach-O format - if it did I would have upgraded years ago ...

[ Hmm, that's an option I hadn't thought of yet - wonder how
  that interferes with the rest of the system, i.e. `ld' which
  is not free. ]

The reason I was thinking about `as -v' output is that it is `as'  
that's failing on your construct, so somehow its version number is
