I'm > assuming it is. It is. You *get* the characteristics of the machine you are compiling on [1]. You *want* the characteristics of the machine your compiled stuff is supposed to be run. There is no simple solution to this problem, IMHO, short of... say building a `probe' program you send to the target machine to collect characteristics and `bring them back' to the compilation host. Does auto-* have such a thing? ------- [1] To be more precise ...the machine you are running configure on.
