problem installing gcc 2.95.2 on m68k-coff (fwd)

[Meir Hacohen]

Hello,

  Thanks for your help. I checked some things and now I got another error :

**************************************************************************

I look for this variable - N_BINCL - in some places, and I really do not
find it. Can you help again ?
