Compiling GNU cc-1.37.1 under IRIX 3.3.1

[Knobi der Rechnerschrat]

Hallo,

  I've fianlly succeded in installing GNU CC 1.37.1 (from prep.ai.mit.edu)
under IRIX 3.3.1. I had to change 7 files in the distribution. I've
included my diffs at the end of this message. Maybe someone with more
knowledge of gcc may have a look at them to see whether something is
missing or totally wrong.

 The main breakthrough (compared to my earlier mail) was the handling of
varargs. It turns out, that under 3.3.1 'va_list' is (depending on the exist-
ence of symbol _VA_ALIST_) typedefed in several instances (stdio.h, stdarg.h,
varargs.h). The solution was to move all occurences of "gvarargs.h" above
<stdio.h> and to define _VA_ALIST_ in va-mips.h for the SGI. This may
mean that you always have to include varags.h before stdio.h when using gcc.
(Question to SGI: Is it possible to keep the definition of va_list totally
in varargd.h ?).

 I've also changed the set of gcc-cpp's predefined symbols to conform with
the SGI cpp. I hope my list is complete. (Question: is there a way to tell
cpp to dump all its predefined symbols?).
