Re: Port of pari/gp 2.7.5 on AIX

["REIX, Tony" <tony.reix@atos.net>]

<green> & <cyan>  ????
I cannot distinguish the 2 colors !
I've tried with a colleague on another display, and that's the same !
I would suggest to use 2 colors that are really different.

About performance, my goal is to check that there is no test where performance on AIX is abnormally lower than it should be compared to linux/intel. So, are you saying that this check is impossible ?

Thx

Tony
