I suppose I can do quite some testing in this case: with PTXdist I can easily build complete Linux userland systems for quite a lot of strange embedded processors (ARM, PPC, MIPS) and test if it works under these circumstances. > I do think Dan's plan to use a special configuration file that needs > to perform no probing will work ??? that is more or less what > non-autoconf cross compilation entails anyway.

Normally things work quite fine if C code ist only compiled with the right cross compiler; some things like endianess have to be taken into account, what else? > What category is this problem: easy or possible?

(Robert is likely screaming: "Your > re-inventing autoconf!!!") How did you know :-) It's just my experience that people normally start with thinking that they can do it much easier than autoconf, and in the end there come more and more requirements, scripts become more and more compilcated and in the end you have something like autoconf but without the huge ammount of experience which went into the system, so working in less situations and being incompatible.
