4.6 only rejects the first one:
t.cc: In function 'int main()':
t.cc:17:18: error: no matching function for call to 'A<int>::a(int (&)(int,
int), int)'
t.cc:17:18: note: candidate is:
t.cc:5:3: note: template<class RES, class ... FARGS> static void A::a(RES
(*)(FARGS ..., SARGS ...), FARGS ...) [with RES = RES, FARGS = {FARGS ...},
SARGS = {int}]
