From Patrice Mandin: "Just a request about test subdirectory: the autotools files (config.guess, config.sub, etc...) are a bit outdated, and I have to update them for my cross-compilation party. So it would be nice to have these updated. ... Just removing these files works, because then configure will use those of SDL's topdir. Could someone else check this, just to be sure? i.e. remove config.guess, config.sub, install-sh and mkinstalldirs from test subdir." I tested on Linux and MacOSX...seems to be safe, so I'm nuking the files. --ryan.
