Re: [patch] testsuite file fails concept-checks

[Jonathan Wakely <cow at compsoc dot man dot ac dot uk>]

The __glibcxx_class_requires macro in include/ext/enc_filebuf.h is at
function scope.  This causes compilation errors in the ext/enc_filebuf
testsuite files when --enable-concept-checks is used since it expands to
a template definition at function scope, which is illegal.

	* include/ext/enc_filebuf.h: Move concept-check macro to class scope.

OK for mainline and 3.4?

N.B.
Most other classes in v3 state the concept requirements at the top of
the class definition, but in enc_filebuf the concept check uses a typedef
which isn't declared until the public part of the class body, so I put
the concept check at the end. I don't think this matters, since in this
case we're not checking a user-supplied template argument but
std::__enc_traits, so visibility of the check isn't important.
