I am trying to intall GCC version 2.1 on our ns32532 box running
Genix version 3. I have managed to compile stage0 but only after
changing tm-genix.h file, which included the following line (line 129):

extern int paren_base_reg_printed;

I had to delete "extern", since I did not find where this variable is
created.
I have also used Genix's malloc, since GNU malloc dumped core, and I didn't
yet look at it.
After all this, and after converting libgcc.a with robotussin, I tried to make
stage1 and this is what I got:

mos% make CC=stage1/gcc CFLAGS="-O -Bstage1/"
        stage1/gcc    -O -Bstage1/     -I. -I. -I./config \
          -DGCC_INCLUDE_DIR=\"/usr/local/lib/gcc-lib/ns32k-genix/`awk '{printf "
%s", substr ($4, 2, length ($4) - 3); }' ./version.c`/include\" \
          -DGPLUSPLUS_INCLUDE_DIR=\"/usr/local/lib/g++-include\" \
          -DLOCAL_INCLUDE_DIR=\"/usr/local/include\" \
          -DCROSS_INCLUDE_DIR=\"/usr/local/lib/gcc-lib/ns32k-genix/`awk '{printf
 "%s", substr ($4, 2, length ($4) - 3); }' ./version.c`/sys-include\" \
          -c `echo ./cccp.c | sed 's,^\./,,'`

cccp.c: In function `do_include':
cccp.c:3915: internal error--insn does not satisfy its constraints:
(insn 197 196 198 (set (reg:SI 0)
       (plus:SI (mult:SI (reg:SI 0)
               (const_int 2))
           (mem:SI (symbol_ref:SI ("indepth"))))) 149 {rotrqi3+3} (insn_list 195
 (nil))
   (expr_list:REG_DEAD (mem:SI (symbol_ref:SI ("indepth")))
       (nil)))
stage1/gcc: Internal compiler error: program cc1 got fatal signal 6
*** Error code 1

Any help would be greatly appreciated.
