Hmm, I'm undecided.
Since gnulib-common.m4 already has a macro _GL_GNUC_PREREQ that uses "defined __GNUC__" to protect against complaints when __GNUC__ is undefined, perhaps gnulib-common.m4 should add a macro _GL_CLANG_PREREQ that does something similar for Clang. That should help readability a bit for Clang, just as we've already done so for GCC.
