That would make it much more likely that old configure.in scripts would Just Work, which is a good thing. Maybe configure would take a '--host-run-cmd' option which would tell it how to run executables during TRY_RUN for cross-compilation. This won't always work- sometimes there's just no way to run code on the embedded system- but hey, it'd work for me. - Dan
