Problems building GNU-CC 1.37.1 on IRIX 3.3.1

[Knobi der Rechnerschrat]

Hallo,

  in order to to build GNU g++-1.37.1 on a 70/GT running IRIX 3.3.1
I've first tried to install GNU gcc-1.37.1. After changing one file
(stddef.h) in the gcc distribution I was able to compile the compiler
using SGI's own cc. The real problems start when I use the result of
this step to compile gcc using itself. After changing two more files
(gvarargs.h and config/tm-iris.h) to get over the first 30 or more
files, gcc finally failed building gnulib. The last error message is:

/gcc Program cc got fatal signal 11

  Has anybody successfully installed gcc (with selfcompilation) under
3.3(.x) ? What are the changes to the standard gnu distribution (which
seems to be ok for 3.2)? What do I have to expect for g++ ?

At the end I will include my changes and expalnations why I had to
made them.

 The trailing underscores seem to be new in 3.3.x

  In 3.3.1 va_list is defined in <stdio.h>. This definition is very
incompatible with that in va-mips.h. I have used the systems standard
file instead. Maybe here I made a very bad move.

------------------- config/tm-iris.h diffs --------------------------

  I included the _LANGUAGE_C symbol, as it is used in many standard
include files under 3.3(.x). Most possible, more stuff has to be included
here.
