The following code snippet is wrongly rejected
int main() { sizeof(&main); }
---
main.cpp: In function 'int main()':
main.cpp:1: warning: ISO C++ forbids taking address of function '::main'
---
But the Standard allows that within a sizeof, because according to 3.2/2 it
does not constitute a "use" of main.
--
Summary: &main should be allowed within unevaluated operands.
