Here are the changes that I needed to bring up gcc-1.37.1 on our DECstation
3100 with ULTRIX 4.0.

The problems I encountered were:

stage0 (bringing up stage1/gcc):
stage1 (bringing up stage2/gcc):

1) symout.c (both stages) uses default ./stddef.h which is incompatible
   with ULTRIX 4.0, use in stead /usr/include/stddef.h by changing the
   INCLUDES in the Makefile (see second patch in Makefile)

2) va-mips.h (stage1) contains a workaround for compilers which does not
   handle varargs correctly (ULTRIX 3.1). Because 4.0 has a ANSII cc this
   workaround can be forgotten (see patch in va-mips.h).

3) I got an error in stage1
   ./gcc Program cc1 got fatal signal 11
   I could solve this by using the compile time option -D_XOPEN_SOURCE in
   the Makefile (patch 1), whatever this means.

4) Because the INCLUDES are changed in the Makefile, bison could not find
   config.h. So I cxhanged that into "./config.h" which seems to work. I don't
   know sure if this is really necessary.

Some advices and warnings:
5) If you already have gcc-1.36 then put away /usr/local/lib/gcc-includes.

6) Don't execute the `make includes', as I did! It spoils your
   /usr/local/lib directory!! Even don't execute fixincludes, because the
   ULTRIX 4.0 compiler has already ANSII header files (hiep hoi).


The real reason I installed gcc-1.37 (we had gcc-1.36 which worked nice)
was to get g++ and gdb. I think some of the problems with gcc are also
explicable to the installation of g++. But I still have no g++ ......

Succes with your gcc/g++ hacking,
