48 as an extension in C99 so long as strict POSIX conformance is not
49 requested. They are available only when building with the llvm-clang
50 compiler, as there is no way to support them with the gcc-4.2 frontend.
51 These may be used for static initialization of complex values, like so:
52
53 static const float complex someVariable = CMPLXF(1.0, INFINITY);
54
55 they may, of course, be used outside of static contexts as well. */
