tips on working with 2.95.2 sources (parallel make, SGI)?

[gary at Intrepid dot Com (Gary Funck)]

Hello, our team is doing some work on gcc, using GCC 2.95.2
as a baseline.  We're working on an SGI Irix 6.5 host, but
using mainly GNU based tools (gmake, gcc, etc.).

Couple of questions:

1) We tried building gcc 2.95.2 from scratch, using gmake's
parallel make option ("-j"), but the build fails.  Has anyone looked
into this?  Is there a patch available that will fix the makefile
dependencies so that a parallel make completes successfully?

2) After a successful build, we tried running just "make" in the gcc
directory, but it seems to "forget" to use *gcc* instead of *cc*, which
in fact, doesn't work properly given the way we have things set up.
We see a similar prob. in a language-specific subdirectory
(eg, objc or cp), when just typing "make".  Is there an easy way
around this?

3) Is there a web page that you'd recommend that gives some tips and
tricks for building gcc, and debugging gcc?  (We've read the porting
guide, and various other resources, and have worked with gcc before.
Just wondering if there might be a web page that will help speed up
our re-entry)?
