The problem is -fdiagnostics-urls=never itself seems not working.
Note that if I invoke cc1 directly and put -fdiagnostics-urls=never *before*
the offending option:
echo "" | LANG= ./gcc/cc1 -fdiagnostics-urls=never -Wtarget-lifetime -x c -
cc1: warning: command-line option '-Wtarget-lifetime' is valid for Fortran but
not for C
It works. But if I put it *after* the offending option:
echo "" | LANG= ./gcc/cc1 -Wtarget-lifetime -fdiagnostics-urls=never -x c -
cc1: warning: command-line option '-Wtarget-lifetime' is valid for Fortran but
not for C
-Wtarget-lifetime in the message becomes a link.
However if I invoke the driver (xgcc) -fdiagnostics-urls=never just does not
work no matter before -Wtarget-lifetime or after it.
