Two quick questions in return! :) First, did you use
the patches on the Linux From Scratch website, which
fixes problems with GCC in a MIPS environment?
(Although not using the MIPSEL environment myself, I'm
on a big-endiam system, I learned very quickly that
those patches really are essential.)

The second question is why 4.1.0? 4.1.1 fixes some
nasties, from what I understand, making that the
better of the 4.1.x branch. On the flip-side, 4.0.3 is
the last-known version of GCC that will compile G95
correctly, strongly hinting at remaining issues in
4.1.x that have the potential for generating incorrect
code. (I've not been able to build 4.2.x from SVN for
a while, although it adds some features I would love
to use.)
