I'm attaching Makeconf, but it seems that right executables were
called. I tried to compile your program with both versions of
compiler, and there is indeed a difference:

$ g++ -c test.cc
test.cc: In function `int main()':
test.cc:10: error: call of overloaded `method(double&, long int&)' is ambiguous
test.cc:3: note: candidates are: void method(double, T) [with X = A, T
= long int]
test.cc:5: note:  void method(double, long int) [with X = A]

$ g++-4 -c test.cc
[... no errors here]
