The usual "no such file" - it does not look like an
order issue since the -I -i order looks right, it
just seems that gcc-2.96 does not search the -I'path
for some pre'-include file.

Your hint is right however, that could be fixed with a
fully qualified name - I did just try it and modified
mozilla/Makefile to use
    -include $(MOZILLA_INCLUDE_ROOT)/mozilla-config.h
which does seem to work indeed. So, that's it. Anyway,
here's the error screen before the modification just
for reference:

btw, after changing over in mozilla/*, it proceeds but just
to stop at the next problem in src/*

this is quite obvious however: gcc-2.96 does not default into the
C99-compatible mode where you can declare variables at any
place within a procedure. This can be easily fixed I guess.

Uhmmm, just as a side note (perhaps a bit off-topic), in
my  own projects, I have started to use c99-style for
variable declarations as the default and most source carry
a compatibility macro definition that makes the sources to
compile on traditional pre-C99 compilers as well:

#define ___ {
#define ____ }

foo (int c)
{
      if (!c) return;
      ___ int i = 0;
      for (; i < c; i++)
      {
           ...
      }____;
      return;
}
