Re: [v3] C99 complex math vs. std::complex

(*) By the way, how _GLIBCXX_USE_C99_COMPLEX_MATH relates to
_GLIBCXX_USE_C99? The new autoconf test should perhaps be ANDed with
the existing ones (in GLIBCXX_ENABLE_C99) thus making
_GLIBCXX_USE_C99 more robust?


Another minor thing: at the end of the current GLIBCXX_ENABLE_C99
there is:

 if test x"$ac_99_math" = x"yes"; then
   AC_DEFINE(_GLIBCXX_USE_C99_MATH)
 fi

which apparently is *duplicate* (the test is already present at line 870)
