Thanks! Try -D_POSIX_C_SOURCE=200112. The macro _C99_SOURCE is for pure C99 code and _ANSI_SOURCE for C90 code. Both don't include the header.

The isnan() macro is a new feature of C99 and thus not (yet) part of
C++. Nevertheless you can use -D_GLIBCPP_USE_C99 to include this and
some other non-standard C++ features.
