The attached patches change setup.py and the distutils
compiler modules to allow dynamically loaded modules
that are built against shared libraries to be built
with the appropriate runtime library search directories
set as needed. The attached patches and a description
of what they do follows:

1. uw7_setup.patch
   This patch modifies setup.py to:

   • have find_library_file() search for the
     directory where a given library file is lo-
     cated, and returns a tuple '(dirs, rt_dirs)'
     where 'dirs' is a possibly-empty list of
     additional directories and 'rt_dirs' is a
     possibly-empty list of directories to be
     searched at runtime. If the file couldn't be
     found at all, None is returned.
   • use the modified find_library_file() to set the
     runtime_library_dirs parameter to Extension()
     method so that the appropriate linker option to
     embed the runtime library directory search path
     in the dynamically load module will be gener-
     ated. Whether or not the option is generated
     is controlled by the distutils compiler class.
   • add the curses and terminfo library to the
     libraries searched when the readline module is
     built.

2. uw7_ccompiler.patch
   This patch modifies Lib/distutils/ccompiler.py as
   follows:

   • The runtime_library_dir_option() method was
     change so that it returns an empty list instead
     of raising the NotImplemented exception. This
     was done so that a reasonable default will be
     used for those systems that do not need to
     specify a runtime search path for libraries.
     It is possible that setup.py will determine
     that a directory will be needed to be searched
     at runtime, even if a particular system or
     compiler do not support or need to have a
     runtime directory search patch defined. In
     this case, the compiler class should return an
     empty list when runtime_library_dir_option() is
     called.
   • Changed how runtime_library_dir_option() is
     called. Instead of calling it once for each
     directory in the runtime_library_dirs list, it
     is called once, passing it the entire list of
     directories to be searched at runtime. This
     pushes the decision of how to format the option
     to the system specific compiler class. Some
     systems (UnixWare, for example) only allow a
     single -R option to be specified, followed by a
     colon (:) separated list of directories to
     search.
   • Added support for a new compiler class,
     USLCcompiler. This compiler class supports
     Unix System Labs style C compilers. UnixWare
     uses this compiler class. Sun's native
     compiler for Solaris use to be based on the
     Unix System Lab's C compiler. I don't know if
     this is still the case.

3. uw7_unixccompiler.patch
   This patch modifies Lib/distutils/unixccompier.py
   so that is no longer defines it's own version of
   runtime_library_dir_option(). Most system's that
   used this compiler do not need to specify a runtime
   directory search path via an ld option.

4. uw7_msvccompiler.patch and uw7_mwerkscompiler.patch
   These patches update Lib/distutils/msvccompiler.py
   and Lib/distutils/mwerkscompiler.py so that being
   passed something in runtime_library_dirs does not
   raise an exception. They will now print a warning
   message if runtime_library_dirs is not empty or
   None. They will return an empty list if
   runtime_library_dir_option() is called.

5. uw7_uslccompiler.patch
   This patch adds the USLCCompiler class.

A new version of the setup.py patch, uw7_setup_2.patch has
been uploaded. This takes info account the recent change to
setup.py in regards to the bsddb module. Please use this
patch in place of uw7_setup_2.patch.

There is apparently no interest in this patch, so I'm
rejecting it.
