Re: AIX build very slow

[Carlo Corridore <carlo at alenianola dot finmeccanica dot it>]

I had the same problem with Aix 4.3.3.
It seems that Aix, during configuration, decrease the priority
of the configuring shell.
It goes faster changing configuring shell with bash Shell
(CONFIG_SHELL=/usr/local/bin/bash) before configure.


Bye.
