This is the same as:
  AC_SEARCH_LIBS(nanosleep, rt posix4, AC_DEFINE(HAVE_NANOSLEEP))
AC_SEARCH_LIBS will first search for nanosleep() with no libraries
linked in, then iterate through -lrt and then -lposix4.

Also, acconfig.h is deprecated. With the following, you don't need a
HAVE_NANOSLEEP entry in acconfig.h:
  AC_SEARCH_LIBS(nanosleep, rt posix4,
    AC_DEFINE(HAVE_NANOSLEEP, 1, [If nanosleep() is available]))
