You mean the version with the IntType first parameter? No, they are right.
IntType must be deduced identically in the two contexts for the template to
be considered a candidate.
The original version should work with gcc/bcc, however. It's only MSVC that
erroneosly overdeduces. :-)
On MSVC the best workaround I've come up with is to add an additional
template<class IntType, class IntType2> void f(IntType1,
This declaration doesn't ensure that IntType is convertible to IntType2, but
the definition should catch this case.
