Bug#126703: g++-3.0: <stdio.h> defines _GNU_SOURCE with g++-3.0

[Philippe Troin <phil@fifi.org>]

Package: g++-3.0
Version: 1:3.0.2-4
Severity: normal

As the title says.

Try this program:

#include <stdio.h>
int main() {
#ifdef _GNU_SOURCE
printf("LOADED\n");
#endif
}

Compile it with "g++-3.0 foo.cpp"

Run it:

$ ./a.out
LOADED
$

This is evil ;-)

Phil.
