Build Problems: AIX 5.2, GCC 4.0.2, xlC 8.0

[Perry Smith <pedz at easesoftware dot com>]

Hi,

I am not sure what to include to make this report usable.  Please ask  
me for whatever extra info you need.

I have a fresh clean AIX 5.2 install (no updates).  I have a fresh  
clean gcc 4.0.2 from a tar ball.  My starting compiler is xlC version 8.

I use the script below to compile.  Eventually I get this message:

Comparing stage2 and stage3 of the compiler
   ... SNIP ...
Bootstrap comparison failure!
./fold-const.o differs

Bugzilla Bug 17777 is this same problem.  It was closed; looks like  
folks were eventually not able to recreate it.  I don't know if I  
should reopen it -- I don't know if I can even.  I've never done that.

I capture the config and make output so I have the whole log to  
review.  FYI, I have three fold-const.o's in my build directory at  
this point and they all have a different size and checksum.

It may be key that I have applied no updates to this version of AIX.

I'll likely try and download a working copy of gcc to bootstrap from  
and move on.  But I'm happy to help try and debug this.

Thank you for your help,
Perry
