granted, it is possible that a different gas was used, but extremely
unlikely. I have been known to build my own compilers (need to try libc
some time), but haven't played around w/ binutils. box is Redhat 6.[01]?
upped to Mandrake 7.1 a month ago.

haven't installed any new compilers lately, I think that 2.4.1 makefile
is different, selects diff compiler (haven't found out the differences
btwn Mandrake and RedHat yet)

grepped sources for that #define; did not find anywhere

Sorry for bad grammar, usually not this bad, very very tired, can't make
fingers type straight half the time.

currently running 2.4.1 rebuilt with mem=192M. Hope this is resolved soon.
Also will consider trying to specify compiler to be same as 2.4.0 build
(not likely a good idea, given that pgcc 2.95.x borks 2.4.1
[fxsr_alignment IIRC])

Also will look for different as executables. BTW, pgcc above is actually
2.95.3, not 2.95.2

I'm rambling and need sleep.
