--- Comment #18 from Richard Nolde <richard.nolde at cybox dot com> 2011-02-24 01:16:22 UTC ---
I'm building gcc-4.5.0 from the current GNU archive on AIX 6.1 (oslevel -s
returns 6100-06-03-1048) using gcc 4.2.4 and the native AIX ld, as, ar, nm, and
ranlib. I do not have any GNU binutils packages installed but I do have bash,
GNU make, and a full compliment of GNU tools in the /opt/freeware tree where
they are typically installed on AIX. I've built numerous other large open
source packages successfully.

I've applied the patch to gcc/xcoffout.c that is provided at the bottom of this
thread. Configure runs successfully but the build fails at this point (full
logs of configure and make output are available:

Let me know if I can provide additional information or logs. It appears that
line numbers are exceeding 65536 for at least some of the errors.
I have run make distclean between each build followed by ./configure
--prefix=/opt/freeware and configure seems to find the correct native utilities
without a problem.
