dll.c includes dl.h if it's found and if libdld is found and contains
the function shl_load(). This is used for HP/UX originally.

Where does the ".dylib" come from? Is this a MacOS thing? I mean, it
sound funny that installing a "dlcompat" package renders the library
loading system incompatible to most other Unixes :-)

Our configure script already knows about the dylib suffix (from
libtool.m4?) but I guess some code needs to be added to dll.c to be
able to load both .so and .dylib.

Maybe something like this:

#if defined(HAVE_DLOPEN)
# define PREFIX "libsane-"
# ifdef __hpux
#   define POSTFIX ".sl.%u"
# elif defined(IS_DARWIN) && defined(HAVE_DL_H)
#   define POSTFIX ".%u.dylib"
# else
#   define POSTFIX ".so.%u"
# endif

Now someone has to find out how to spell defined(IS_DARWIN) and if
this works for both the .so and .dylib cases.

Bye,
