I've done many benchmark on diffrent PC's (486, 586 and 686). It seems that
the g77 compilator is less efficient the f2c translator. I don't no what's
happend on other Unix. Moreover, gcc optinisations aren't futile (I've test
a binary distribtion compiled for Pentium on a PPro and an other compiled
specialy for PPro). I've mirrored octave sources and some binary distribtions
for Linux on my ftp server (beijing.univ-mlv.fr). If it can help someone...
