I do not think this can be done in *compiling* time, neither macro in
c nor template in c++, so would you be so kind to offer the solution
by using template or just give  some tips? Since I'm not that good at
c++ :)

I was thinking along the lines of:

template<unsigned offset>
struct _filename {
	static const char *const val = __FILE__[offset] == '/'
		? __FILE__ + offset + 1
		: _filename<offset-1>::val;

struct _filename<0> {
	static const char *const val = __FILE__;

static const char *const filename = _filename<sizeof(__FILE__) - 1>;

I'm a bit rusty so I dunno if that'll work in this format.
