[Bug c++/40942] GCC accepts code that Comeau and MSVC deems invalid.

Table 9 under 13.3.3/1 shows that array-to-pointer conversion is Exact Match.
As is rvalue-to-lvalue conversion (though string literals are lvalues anyway
:D). As is Identity, which is what applies here.

There is no clear ranking between them, hence Comeau reporting ambiguity.
Although I personally think Identity should overrule absolutely everything, it
doesn't. So IMO GCC is buggy in this way.
