[patch] additional dladdr check in configure.ac

[patch] additional dladdr check in configure.ac

[Andreas Tobler]

Hello,
the attached patch to configure.ac looks for dladdr in libdld.sl on 
HP-UX. If the OS has the right version and patches the check succeeds.

Ok for main?

ok,
as it seems there are other functions waiting.

I had to add dlopen. Since it is there too in libdld.sl.

Ok, for main??

Ok.  Thanks.

You might want to see if you need to add -ldld to SYSTEMSPEC.  Look a
bit later:

   # On Solaris, and maybe other architectures, the Boehm collector
   # requires -ldl.
   if test "$GC" = boehm; then
      AC_CHECK_LIB(dl, main, SYSTEMSPEC="$SYSTEMSPEC -ldl")
   fi

I don't mind if that is a separate patch though, up to you.
