Hello Henning,

I have applied your patch now, including a NEWS entry, as below, and put
you in THANKS.  Please check that I did not make any errors, thanks.

Gathering from the testsuite failure, the shared library support has
some work ahead yet.

Thank you Ralf

I hope that I will find some more time to make some more tests/changes in
about week.

Best regards,
Henning

  Since July 2007 AmigaOS4 officially supports .so libraries. It would
 be
  nice if it would be possible to add support for it in Libtool. The
  attached patch does make it working.
 
  Thanks a lot for the patch.  Apart from minor version skew-induced
  hunks, it looks good to me.  Could you be bothered to run the
 testsuite
 [...]
 Sorry for the delay, but here is my result, using a crosscompilation
 suite
 on cygwin. The test was running on libtool-2.1b with my changes - patch
 #6416

 It will be more difficult to make the test native, as we do not have a
 new
 enough version of automake/autoconf running on AmigaOS4. But I will do
 mine to test it this weekend.

 It's fine if you do cross compilation testing.

 What I'd like to know though before applying the patch: are there
 systems other than m68k and powerpc on which AmigaOS runs?

No, it is only m68k and PowerPC.

 Do we have to maintain backward compatibility to AmigaOS versions earlier
 than the one that supports shared libraries?

ppc-amigaos (AmigaOS4) is supporting shared libraries. The update that
enabled shared libraries is an official update, that is free for people
owning AmigaOS4.

 And then, you remove this comment:

 -  # Samuel A. Falvo II [EMAIL PROTECTED] reports
 -  # that the semantics of dynamic libraries on AmigaOS, at least up
 -  # to version 4, is to share data among multiple programs linked
 -  # with the same dynamic library.  Since this doesn't match the
 -  # behavior of shared libraries on other platforms, we can't use
 -  # them.

 Is this issue now fixed?

Some people are still using it, but I do hornestly do not know how many
people is using it (and why it was removed from libtool). It does not
matter much for me, as I am only an AmigaOS4 user and there is not that
much work done on classic (m68k) AmigaOS anymore.

 Thanks,
 Ralf
