Section 22.214.171.124 [member.functions] makes it clear that standard library implementers are allowed to "replace a member function with default arguments with two or more member functions with equivalent behavior". However, it is unclear when reading 126.96.36.199 [global.functions] whether implementers are allowed to perform the same transformation for non-member functions. 188.8.131.52 [global.functions] p3 mentions that "an implementation shall not declare a non-member function signature with additional default arguments", but does not explicitly forbid to replace a function with default arguments with more functions with equivalent behavior.The standard should make it clear whether such a transformation is conforming or not, probably through a note [global.functions]. Link to the Standard Discussion forum.
We believe that [member.functions]p2 is clear.
