openssh unix dev - Feb 2011 - Compilation error: SEVERE ERROR: Symbol C_BSTAT (entry 2175) in object clientloop.o

Previous version compiled successfully was 5.5p1. Now compiling 5.8p1 on 
the same machine "AIX 5.3 TL12 SP2" via GNU make with gcc 4.2.0 - got 
an error, can someone help with this?

It's a bug in either gcc or recent versions of AIX's linker that 
manifests with static variables when debug symbols are enabled.

I suspect disabling debug symbols at build time would help:

CFLAGS="-O2" ./configure && make

but it's not been confirmed either way.
