Consider this code snippet:
cat x.c
struct test {
void *tst;
};
struct yy {
void **z;
};
int foo(struct test *x)
{
struct yy y[] ={
{ (void**) &x->tst }
};
return 0;
}
$ gcc x.c -c -pedantic
x.c: In function foo:
x.c:10: warning: initializer element is not computable at load time
x.c:10: warning: initializer element is not computable at load time
I now use -Werror:
$ gcc -Werror x.c -c -pedantic
cc1: warnings being treated as errors
x.c: In function foo:
x.c:10: error: initializer element is not computable at load time
x.c:10: error: initializer element is not computable at load time
This is fine, but now I want -Werror (perhaps because I use -Wall or some other
-W flags), but I don't want warnings from -pedantic to be errors (but I still
want to see them!):
$ gcc -Wall x.c -c -pedantic -Werror -Wno-error=pedantic
cc1: error: -Werror=pedantic: No option -Wpedantic
This doesn't work, and I see no other way to downgrade -pedantic to warning
after I used -Werror.

Summary: please provide a way to treat -pedantic as warning when
using -Werror
