Actually, C99's __func__ is neither a macro nor a string literal:
6.4.2.2#1:
The identifier __func__ shall be implicitly declared by the translator
as if, immediately following the opening brace of each function
definition, the declaration
static const char __func__[] = "function-name"
appeared, where function-name is the name of the lexically-enclosing
function.
Thus, the compiler is not lying. However, since a function name cannot
contain a '%' character, and the string cannot be modified (as it is
defined const) the warning is really just noise.
