 * This include file contains ifdefs that tell us if this system has
 * some of the several functions that are not part of POSIX but are
 * often distributed anyway as part of ANSI C.  The set of defines
 * below is automatically assigned by CMake and determines if the
 * required functions are present or not.  These macros are then used
 * to choose between a function prototype (if found), an alternative
 * GMT function, or simply a macro.  The purpose is to take advantage
 * of the built-in functions if they exist and provide alternative
 * definitions otherwise.
 *
 * HAVE_<func> is undefined or defined as 1 depending on
 * whether or not <func> is available on this system.
 *
 * For adding more HAVE_**** checks, see ConfigureChecks.cmake.
