i implemented this, thus findutils can continue like before :) so the previous 
(already pushed) patch is no longer necessary (sorry for consuming your 
time...). actually, the patch is now harmfull, as _SC_ARG_MAX is now the only 
source of "good" information... :[

i will still keep an eye on it on my interix boxes whether this works in all 
situations.

this is IMHO the best solution, as it takes the responsibility from findutils 
to work around existing OS bugs, when there is a library, doing this exact 
thing. there is not even a need to make findutils know libsuacomp, as suacomp 
installs a libc.so and libc.a linker scripts into it's prefix. as soon as this 
path is in the linker path, it works (and in gentoo prefix on interix i have 
linker and compiler wrappers assuring this).

sorry, that i didn't have that idea earlier, would have saved some work for all 
of us.

are you ok with this solution?
