Err, could you please elaborate on this cryptic remark?

Duraid, in all fairness: IIRC it was you who made us try our symbolic
computation code in C++ on some commercial compilers (Intel's was one of
them). You sure remember this was a complete fiasco. Maybe our code is
just strange, because GCC generates the best code on it. ;-)
