- * Check for the existence and support of POSIX timers. The standard
- * says that the _POSIX_TIMERS macro will have a positive value if they
- * are available.
- *
- * However, we want an additional constraint: that the timer support does
- * not require an extra library dependency. Early versions of glibc
- * require -lrt to be specified on the link line to access the timers,
- * so this needs to be checked for.
- *
- * It is worse because some libraries define __GLIBC__ but don't
- * support the version testing macro (e.g. uClibc). This means
- * an extra check is needed.
- *
- * The final condition is:
- * "have posix timers and either not glibc or glibc without -lrt"
- *
- * The nested #if sequences are required to avoid using a parameterised
- * macro that might be undefined.
