--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Another example:
long i = reintepret_cast<long>((void*)0);
cast.C:1:10: error: ‘reintepret_cast’ was not declared in this scope
1 | long i = reintepret_cast<long>((void*)0);
| ^~~~~~~~~~~~~~~
cast.C:1:26: error: expected primary-expression before ‘long’
1 | long i = reintepret_cast<long>((void*)0);
| ^~~~
And this one with -std=c++20:
template<class T>
void
f(const void* v)
{
auto u = reintepret_cast<long>(v);
}
cast.C: In function 'void f(const void*)':
cast.C:5:12: error: there are no arguments to 'reintepret_cast' that depend on
a template parameter, so a declaration of 'reintepret_cast' must be available
[-fpermissive]
5 | auto u = reintepret_cast<long>(v);
| ^~~~~~~~~~~~~~~~~~~~~
cast.C:5:12: note: (if you use '-fpermissive', G++ will accept your code, but
allowing the use of an undeclared name is deprecated)
