Subject: [PATCH] Revert r263694, and apply a better fix to squelch unnecessary
 warnings from clang about possible keywords being treated as identifiers for
 the remainder of the translation unit (a.k.a. -Wkeyword-compat), when using
 libstdc++ in combination with -Wsystem-headers.  This will not only fix devd,
 but any C++ program using libstdc++.
