CLang fails to build angelscript because it won't allow you to typecast a int to a struct:

[source lang="cpp"]
// Define template
template <int N>
struct asSMethodPtr
{
template<class M>
static asSFuncPtr Convert(M Mthd)
{
// This version of the function should never be executed, nor compiled,
// as it would mean that the size of the method pointer cannot be determined.

int ERROR_UnsupportedMethodPtr[N-100];
return 0;
}
};
[/source]

The following change fixes the error:
[source lang="cpp"]
...
int ERROR_UnsupportedMethodPtr[N-100];

asSFuncPtr p;
return p;
...
[/source]

Since CLang is a drop in replacement for GCC, it doesn't require any configuration changes to make native calling conventions work correctly.

Thanks. I've checked in this change in revision 947.
