Hi all, I got this warning during configuration: /Volumes/SandBox/Clean/llvmCore.roots/llvmCore~obj/src/llvm/configure: line 4186: ,: command not found It looks like this is the culprit: case $ac_cv_c_bigendian in yes) ENDIAN=big , (note the ',') This looks like it could possibly fix the problem. I don't have an autoconf that won't mess things up, though.
