Re: Build report for AIX 6.1

[David Edelsohn <dje dot gcc at gmail dot com>]

Mario,

I, personally, have not encountered MAXDATA limits building
application with GCC (as opposed to Java), but I can see that some
large applications might encounter them.  I bootstrap GCC every night
and build many GNU applications with the default GCC configuration.
I can adjust the default GCC bootstrap to include a larger MAXDATA
value.

Is there a particular reason that you use different values on AIX 5.3
and AIX 6.1:  MAXDATA=0x40000000 on AIX 5.3 and MAXDATA=0x50000000 on
AIX 6.1?

Thanks, David
