Nothing against the patch but I would like to see the optimization in
convert.c be moved to fold-const.c instead as fold is used more and more
by the tree optimizators.  Also it will help to cause cases like the following
to be optimizated:

int f(double e) { double e1 = floor(e); return e1; }

Huh, an expert for trees could move all these convert.c optimizations, because they are all similar. Perhaps also a conversion from (int) trunc -> FIX_TRUNC_EXPR could be handled there, although it is a bit silly.

(I'm still learning the misteries of TREE_* stuff :))

Uros.
