Would it be possible to cover -Wp,-D,_FORTIFY_SOURCE… and
-Wp,-U_FORTIFY_SOURCE as well? Some of us used -Wp,-D,_FORTIFY_SOURCE…
for compatibility with the GCJ compiler driver, where
-D_FORTIFY_SOURCE=2 meant something completely different. And now we
are stuck with those variants because some scrits use sed to remove
those flags, assuming the presence -Wp, prefix.
Thanks,
Florian
