Recently I've been trying to get GCC installed on our SGI Challenge
running Irix 5.1.1.  I configure with the command

./configure --target=mips-sgi-irix5

The rest of my script looks like this:

make LANGUAGES=c
make stage1
make CC="stage1/xgcc -Bstage1/" CFLAGS="-O"
make stage2
make CC="stage2/xgcc -Bstage2/" CFLAGS="-O"
make compare

When it reaches the compare stage, it hurls in violent technicolor,
finding differences with every file:

tmp-foo1 tmp-foo2 differ: char 417, line 2
alloca.o differs
tmp-foo1 tmp-foo2 differ: char 111985, line 289
aux-output.o differs
tmp-foo1 tmp-foo2 differ: char 26953, line 30
bc-emit.o differs
    [you get the picture ... hundreds more like these deleted]
varasm.o differs
tmp-foo1 tmp-foo2 differ: char 597, line 2
version.o differs
tmp-foo1 tmp-foo2 differ: char 481, line 1
xcoffout.o differs

Is GCC for SGI not quite there yet?  (At least it seems to know about
ELF now).  Is there something I could do to fix the problem?  Would
2.5.4 help?

When I try running the gcc produced, it behaves rather strangely.  
Here's how it crashes when I try to compile tin 1.22:

        yacc  parsdate.y

The reference to the /usr/local/lib/gcc-lib/mips-sgi-irix5/2.5.3/include
include file is surprising.  Nothing in tin refers to these directories.
I thought these were just for gcc's use when compiling itself.  Should I
just delete this ticking time bomb of a gcc, or is it possibly OK?
