IMHO, Makefiles should I think that installing a variant driver program as "c99", that implements the different semantics, is exactly the right thing to do here; the present semantics are more useful for "gcc". We should have a configure option to install "cc", "c89" and "c99" drivers; they should have appropriate defaults regarding e.g. standards mode, and should also adjust the precedence of these options and make any other adjustments required by POSIX that aren't appropriate for "gcc". -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40960
