I had played around at one point with the idea of c++config.h being
-include'd by all C++ programs, via the default specs. A cow-orker did so
in a local tree, and it caused problems all over the place. IIRC some C++
feature tests were failing during autoconf. We concluded that we didn't
know how to properly augment the lang-specs file...
Anyhow, since c++config.h includes os_defines.h, this approach would
obviate the need for CPLUSPLUS_CPP_SPEC on AIX and the like. Just put
the defines in os_define.h and every translation unit will see them.
