You got it.

Aaaaargh!

Uhm.  Try `ls -l /usr/bin | grep egc'.  Probably you have a binary
(I'm betting on `egcc') which invokes the egcs instance of gcc rather
than gcc 2.7.2.3.  This may pick up a symlink or perhaps a alias like
i386-pc-linux-gnu-egcs-gcc, too.

Several of the packages I've worked with lately (in particular
glibc-2.1 but also binutils I think) strongly recommend compilation
with egcs as "gcc 2.7.x is fatally buggy".  AFAIK the ONLY reason now
for using gcc 2.7 instead of egcs >= 1.1 on x86 architectures is that
the kernel code is buggy (it relies on "illegal asm clobbers"
according to Chris, whatever that means).
