bootstrap failure with old version of egcs (1.0.3a)

[Paul Forgey <paulf at aphrodite dot com>]

I'm restoring an AIX build box, which needs to run 1.0.3a (unfortunately)
to do some historic builds.  I'm using binutils-2.8.1, configured:
--prefix=/usr/local/1.0.3 --host=powerpc-ibm-aix4.2
--target=powerpc-ibm-aix4.2 egcs-1.0.3a, configured:
--prefix=/usr/local/1.0.3 --host=powerpc-ibm-aix4.2
--target=powerpc-ibm-aix4.2 --enable-shared --with-gnu-as --with-gnu-ld
and -D_LONG_LONG added to gcc/config/rs6000/aix41.h I'm also adding
/usr/local/1.0.3/bin to the PATH (first in search order) before
configuring and building egcs.

The operating system itself is actually AIX 4.3, but I know the compiler
was installed as powerpc-ibm-aix4.2 before, on 4.3.  I'm using gmake
version 3.78.1.

Here's the problem; make bootstrap builds the stage1 compiler OK, however
after doing so:

ln cccp cpp ln: cccp: A file or directory in the path name does not exist.
make[2]: *** [cpp] Error 1 make[2]: Leaving directory
`/home/paulf/software/egcs-1.0.3a/objdir/native/gcc' make[1]: ***
[bootstrap] Error 2 make[1]: Leaving directory
`/home/paulf/software/egcs-1.0.3a/objdir/native/gcc' make: *** [bootstrap]
Error 2

./gcc/stage1/cccp does exist at this point.. Help..??

Thanks.
