[Bug c++/22549] New: Differing error messages depending on thelocality of a variable

["theodore dot papadopoulo at sophia dot inria dot fr" <gcc-bugzilla at gcc dot gnu dot org>]

While looking at having a better error message (giving types in the message
"operands to ?: have different types", I found a strange behaviour of gcc.

When a variable is declared local (a function parameter) it gives the message
"no match for 'operator-'" and when declared global it gives the above
mentionned message. I'm attaching a testcase. This is for mainline but was
already true for 3.4.3.
