-It would be very useful if autoconf allowed checking for multiple libraries
-that are required together. For example:
-
-AC_HAVE_LIBRARY([-lsocket -lnsl], [LIBS="$LIBS -lsocket -lnsl"])
-
-I have been informed that SVR4 requires both -lnsl to be used with -lsocket,
-so a test just for -lsocket fails, as that will not compile.

-- I would like the default behavior of the library command to change
-so that the newly tested library is tried in front of $LIBS instead of
-after it. This makes it possible to test for more complicated sets of
-dependencies. For instance: on some SVR4 systems (e.g. Sequent),
--lsocket requires -linet and -lnsl. The link order must be
-"-lsocket -linet -lnsl". On some other SVR4 systems either -linet or
--lnsl does not exist. Now if I test for -lnsl first, the test for
--linet fails because it tries "-lnsl -linet"; but if I test for
--linet it fails because it only works if -lnsl is also specified.

+
+In libc and make in aclocal.m4 I have AC_CHECK_SYMBOL, which checks for
+sys_siglist et al. Using AC_CHECK_FUNC doesn't work on some system that
+winds up caring that you reference it as a function and it is really a
+variable. My version always declares the symbol as a char *[]; if that
+ends up a bad idea, we can have it take an arg with the C decl, but that is
+a bit verbose to write if it's actually superfluous.
+From Roland McGrath.
+
+------------------------------------------------------------------------------
+
+In /gd4/gnu/hurd/aclocal.m4 I wrote AC_CHECK_TOOL, which is a boon when
+doing a lot of cross compilation, and I think a good thing to use
+generically (AC_PROG_{CC,RANLIB} should use it). I want this merged so I
+can convert mach4's configure.in to stop using local hack macros, and
+finally get a configure.in up for hurd (and then rewrite its makefiles
+again).
+From Roland McGrath.

+------------------------------------------------------------------------------
+
+ ls -lt configure configure.in | sort
+doesn't work right if configure.in is from a symlink farm, where the
+symlink has either a timestamp of it's own, or under BSD 4.4, it has
+the timestamp of the current directory, neither of which
+helps. Changing it to
+ ls -Llt configure configure.in | sort
+works for me, though I don't know how portable that is

+LIBS=$LIBS $PKG-LIBS
+DEFS=$DEFS $PKG-DEFS
