[Bug c++/38780] New: upgrade warning to error for bad C++ code ?

[dcb314 at hotmail dot com]

I just tried to compile the following C++ code
with the GNU C++ compiler version 4.4 snapshot 20090102.

extern int f();

void
g()
{
        f + 27; // should fail
}

The compiler said

bug50.cc: In function 'void g()':
bug50.cc:9: warning: pointer to a function used in arithmetic

Here is gcc 4.3.2 on the same code - this is closer
to the language definition

bug50.cc: In function 'void g()':
bug50.cc:9: error: pointer to a function used in arithmetic

I suspect that the warning in 20090102 needs to be upgraded
into a warning.
