General shared library improvements for CYGWIN / AIX
Description:
Shared libraries are disabled on both CYGWIN and AIX due
to inability to build them correctly. Part of the problem
in both of these situations is the lack of the libtool
flag -no-undefined, which tells libtool that all needed
symbols are defined at link time (a requirement on these
systems) and that it's okay to build shared libraries.
Another problem are lack of dependencies between wrapper
libraries and core C HDF5 library.
This patch addresses both of these by fixing configure to
add in -no-undefined flag for libtool during linking and
adds automake dependencies in the Makefile.am files.
After testing, both CYGWIN and AIX now generate shared
libraries, but there are still some test failures in each.
(cache_api, dt_arith, and testerror.sh on CYGWIN, and
fortran tests on AIX).
Even though the shared libraries are not quite perfect,
this is a general improvement to what we had before, so
I'm applying the patch anyways. Note that default behavior
of shared libraries on these systems being disabled has
NOT been changed and requires the use of the
--enable-unsupported to attempt to build them.
We will need to address the test failures in each
architecture prior to formally supporting shared
libraries on each.
Tested:
h5committested & CYGWIN tested (on bangan)
(AIX tested by Albert on bp-login2)
