Thanks for your answer! Concerning qt and optimization, I should
insist. I wrote certain qt applications. Certain redraw events in a
list window take lots of time (no IO). The delay is impressing
concerning raw athena widgets (which I am using alternatively). So I
think that optimization can be essential.

PS. My last remark is probably not correctly placed on this list:
Opposed to C, f77 contains a lot of context information which can be
used in order to speed up programs. As far as I know, Fortran
optimization belongs to the best investigated issues. Does g77/pg77
use any of these techniques? M.
