-# SYNOPSIS
-#
-#   AX_HAVE_EPOLL([ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
-#   AX_HAVE_EPOLL_PWAIT([ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
-#
-# DESCRIPTION
-#
-#   This macro determines whether the system supports the epoll I/O event
-#   interface. A neat usage example would be:
-#
-#     AX_HAVE_EPOLL(
-#       [AX_CONFIG_FEATURE_ENABLE(epoll)],
-#       [AX_CONFIG_FEATURE_DISABLE(epoll)])
-#     AX_CONFIG_FEATURE(
-#       [epoll], [This platform supports epoll(7)],
-#       [HAVE_EPOLL], [This platform supports epoll(7).])
-#
-#   The epoll interface was added to the Linux kernel in version 2.5.45, and
-#   the macro verifies that a kernel newer than this is installed. This
-#   check is somewhat unreliable if <linux/version.h> doesn't match the
-#   running kernel, but it is necessary regardless, because glibc comes with
-#   stubs for the epoll_create(), epoll_wait(), etc. that allow programs to
-#   compile and link even if the kernel is too old; the problem would then
-#   be detected only at runtime.
-#
-#   Linux kernel version 2.6.19 adds the epoll_pwait() call in addition to
-#   epoll_wait(). The availability of that function can be tested with the
-#   second macro. Generally speaking, it is safe to assume that
-#   AX_HAVE_EPOLL would succeed if AX_HAVE_EPOLL_PWAIT has, but not the
-#   other way round.
