libstdc++: Stop defining C++0x compat symbols for versioned namespace
The src/c++11/compatibility*-c++0x.cc files define symbols that need to
be exported for ancient versions of libstdc++.so.6 due to changes
between C++0x and the final C++11 standard. Those symbols are not needed
in the libstdc++.so.8 library, and we can skip building them entirely.
This also fixes the build failure I introduced last week when making the
versioned namespace config not use the _V2 namespace for compat symbols.
libstdc++-v3/ChangeLog:
* src/Makefile.am [ENABLE_SYMVERS_GNU_NAMESPACE] (cxx11_sources):
Do not build the compatibility*-c++0x.cc objects.
* src/Makefile.in: Regenerate.
* src/c++11/compatibility-c++0x.cc [_GLIBCXX_INLINE_VERSION]:
Refuse to build for the versioned namespace.
* src/c++11/compatibility-chrono.cc: Likewise.
* src/c++11/compatibility-condvar.cc: Likewise.
* src/c++11/compatibility-thread-c++0x.cc: Likewise.
* src/c++11/chrono.cc (system_clock, steady_clock):
Use macros to define in inline namespace _V2, matching the
declarations in <system_error>.
* src/c++11/system_error.cc (system_category, generic_category):
Likewise.
