--- Comment #1 from Ian Lance Taylor <ian at airs dot com> --- I don't understand your patch, because I don't understand where CONFIG_USE_MUSL gets set. It also seems like the wrong approach. The basic goal of configure tests is to test for features, not systems. mksysinfo.sh already works that way. What fails without this patch?
