Very old IBM RS/6000 machine (model 320H) running under AIX-4.2.1 (rs6000-ibm-aix4.2.1.0),
binutils-2.13, "--with-gnu-as" etc, gnu make
>Description:
During "make bootstrap", I get the following error message:
if [ -f stmp-dirs ]; then true; else touch stmp-dirs; fi

Everything is OK if I use a newer machine (F40)
(powerpc-ibm-aix4.2.1.0).

I'm going to rerun the bootstrap procedure
without requesting usage of GNU as/ld. I expect
this to work, at least it worked on GCC-3.1 and 3.1.1.
>How-To-Repeat:
- gzip -cd gcc-3.2.tar.gz|tar xf -
- patch -p0 <gcc-3.2-aix42.diff (see attachement)
- mkdir gcc-3.2-build
- cd gcc-3.2-build
- ../gcc-3.2/configure --prefix=/usr/local\
   --with-gnu-as --with-as=/usr/local/bin/as\
   --with-gnu-ld --with-ld=/usr/local/bin/ld
- /usr/local/bin/make bootstrap
