    1 Hacking gcc (almost died from recursion)
    2 ----------------------------------------

    4 Analysing gcc works properly by replacing the variables
    5 
    6 	CC = gcc
    7 	AR = ar
    8 to
    9 	CC = ncc -ncgcc -ncld -ncfabs
   10 	AR = nccar
   11 
   12 In the Makefile in the objdir, near the comment

   15 	Programs producing files for the HOST machine

   18 HOWEVER, this does not work right away. 
   19 What I did was.
   20 
   21 - first compile gcc with "make bootstrap" with the
   22   original CC and AR values (without ncc)
   23 
   24 - then edit the Makefile and add ncc/nccar
   25 
   26 - then go to the gcc source inside the gcc/ directory
   27   and do "touch *.h"
   28 
   29 - then go to the objdir and redo "make"
   30 
   31 That seemed to work but it takes ages. The problem was
   32 libiberty. If anyone improves that, send mail.
