Thanks, I am busy testing `AC_LIB_LINKFLAGS' now. The fact that it 
modifies CPPFLAGS and adds `rpath' when necessary is great.

However, from the outputs of `make', I noticed that it doesn't use 
`LTLIB<NAME>' (which contains the `-L' option for the library's directory).

As a result on a system with two versions of a library, compilation 
passes with the proper version of the library header (when using the 
correct `-I' with the updated `CPPFLAGS'). However, during linking, it 
links with the wrong version and we get a crash with a linking error.

How can I get the `-L<LIB_PATH>' part of `LTLIB<NAME>' into LDFLAGS?

I am thinking of adding a loop manually in `configure.ac' to do this for 
all the libraries I need, but before that, I am confused why 
`LTLIB<NAME>' isn't being used by libtool as suggested in the Gnulib 
manual: "The macros also set a variable LTLIB<NAME>, that should be used 
when linking with libtool."

Thanks a lot,
Mohammad
