AIX 5.3 gcc 4.1.2 bootstrap error

[Jonathan Saxton]

Brian:

Yes I knew about that and I had been careful to supply the appropriate
"--with" options to the configure script.  What I didn't know was how
aggressive the stage 3 configuration was in searching for the gnu tools.  I
only discovered the problem because I just happened to be watching the
screen at the moment stage 3 started.  Of course everything scrolled off too
quickly for me to read but a repeat of the build piped through tee showed
"Target ld ..." and "Target as ..." to be something other than the native
AIX tools.  I purged all traces of binutils and everything worked.

Subsequently I did restore cxxfilt because that is useful and harmless but I
think a warning should be added to the text which you mentioned.

For what it's worth gcc documents this requirement:
