gcc 4.0.0 and OCaml 3.08.3

gcc 4.0.0 and OCaml 3.08.3

[Bill Smith]

I've been having trouble with the "make world" phase of compiling OCaml 
3.08.3 with gcc 4.0.0.

I'm using Linux 2.4.26 on an AMD Athlon XP.

There error I get is:

/gcc-4.0.0/bin/gcc -O2 -O -I../../byterun -D_FILE_OFFSET_BITS=64 
-D_REENTRANT -fPIC -DBNG_ARCH_ia32 -DBNG_ASM_LEVEL=2   -c -o bng.o bng.c
In file included from bng.c:21:
bng_ia32.c: In function 'bng_ia32_mult_add_digit':
bng_ia32.c:111: error: can't find a register in class 'GENERAL_REGS' while 
reloading 'asm'
make[1]: *** [bng.o] Error 1

To deal with the problem I've just fallen back to gcc 3.4.3 which compiles 
ocaml 3.08.3 successfully.

We (debian/ubuntu ocaml maintainers), filled a bug report in the debian BTS
about this exact same problem a week or two ago, didn't check for any reply
there thoguh.

Notice that this only affects ia32, but not powerpc, amd64 or ia64, so maybe
it is best to just ditch those legacy hardware :)
