259	<	dnl
260	<	dnl Synopsis:   mdw_CHECK_MANYLIBS(FUNC, LIBS, [IF-FOUND], [IF-NOT-FOUND])
261	<	dnl
262	<	dnl Arguments:  FUNC = a function to try to find
263	<	dnl             LIBS = a whitespace-separated list of libraries to search
264	<	dnl             IF-FOUND = what to do when the function is found
265	<	dnl             IF-NOT-FOUND = what to do when the function isn't found
266	<	dnl
267	<	dnl Use:        Searches for a library which defines FUNC.  It first tries
268	<	dnl             without any libraries; then it tries each library specified
269	<	dnl             in LIBS in turn.  If it finds a match, it adds the
270	<	dnl             appropriate library to `LIBS'.
271	<	dnl
272	<	dnl             This is particularly handy under DIREIX: if you link with
273	<	dnl             `-lnsl' then you get non-NIS-aware versions of getpwnam and
274	<	dnl             so on, which is clearly a Bad Thing.
275	<	dnl
276	<	dnl Modified:   by Evgeny Stambulchik to add (found) libraries to `LIBS'
277	<	dnl             *only* if `IF-FOUND' is absent. As well, if no additional
278	<	dnl             library is needed for `FUNC', `mdw_cv_lib_$1' sets to "".
