I guess, this is at the moment a little bit too tricky for me to try. I
am a biologist, not a programmer (got stuck after 2/3 of "(dirty) C for
Dummies" ... ;-) ). Thank you for that tip anyway, perhaps I will be
able one day to roam around C-source codes by myself and optimise. Since
my first alien attempts didn´t work out too well (the Compaq compiler
and math lib were my first try ever to debianise something), I just
decided to have at first a working gcc with libffm and give it a little
more time to find out about the ccc things to consider.
