--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
clang does a reasonable job at their error message here:
<source>:2:5: error: function-like macro 'sizeof' is not defined
#if sizeof(int) > 4
^
ICC is almost as bad as GCC:
<source>(2): error: function call is not allowed in a constant expression
#if sizeof(int) > 4
^
MSVC is worse than GCC:
<source>(2): fatal error C1017: invalid integer constant expression
