------- Comment #2 from manu at gcc dot gnu dot org 2009-08-07 13:07 -------
This is because neither Werror= nor #pragma GCC diagnositcs work with "group
flags", that is, flags that enable other flags.
Until this is fixed, you need to give exactly the flag reported by
-fdiagnostics-show-option, so in your case it would be:
-Werror=implicit-function-declaration
if none is reported that is also a bug, so open another PR.
