From: Luc Grosheintz <[email protected]>
When running the tests without pre-compiled headers
(--disable-libstdcxx-pch), the test fails, because the feature
testing macro (FTM) isn't defined yet.
This commit moves checking the FTM to a dedicated file (version.cc)
that's run without PCH.
libstdc++-v3/ChangeLog:
* testsuite/20_util/function_objects/not_fn/nttp.cc: Move
test of feature testing macro to version.cc
* testsuite/20_util/function_objects/not_fn/version.cc: New test.

v3 fixes one instance of FMT with FTM.
Having a separate version.cc for FTM makes sense in context if we would run
tests
with import std.
