I don't see how that would be a problem, but won't this pollute POSIX
namespace?  The older POSIX standard includes all ANSI C89 functions,
but not all C99 functions (if any; I haven't checked).  So that #if
should also check for strict POSIX compliance, and if it's required,
what version of POSIX is requested (presumably the newer POSIX includes
all ANSI C99 functions).  If there are any functions that are both C99
and older POSIX, they need yet another section with its own test.
