handle OSError and DistutilsExecError now.

rather than None.

Fixed 'build_extensions()' to pay attention to the 'rpath' element of the
  'build_info' dictionary.

  we don't know what to do with it when we see it.
Call '_fix_object_args()' and/or '_fix_lib_args()' as appropriate, rather
  than just '_fix_link_args()'.

  use it when linking.
Call '_fix_object_args()' and/or '_fix_lib_args()' as appropriate, rather
  than just '_fix_link_args()'.

Split '_fix_link_args()' up into '_fix_object_args()' (for use of
  'create_static_lib() and link methods) and '_fix_lib_args()' (for the
  link methods only).

returns a value.

Deleted some crufty code.

completely (was already commented-out).

Python modules, pure and extensions.

Python and extensions, into the same directory.

longer needed, and can't possibly work anyways.

these must come from the 'build' command.  This means we no longer need
the misconceived 'set_peer_option()' method in Command and, more importantly,
sweeps away a bunch of potential future complexity to handle this tricky
case.

Tightened up some logic in 'native_path()'.
Added 'subst_vars()' and '_check_environ()'.

Fix 'Command.set_undefined_option()' to call 'ensure_ready()' rather
  than 'finalize_options()' (which is only supposed to be called once,
  which is the whole point of 'ensure_ready()').
Added comment to 'set_peer_option()' to remind myself that this method
  cannot work and is fundamentally wrong-headed.

this command for a while; this implements roughly the plan cooked up by
Guido, Fred, and me.  Seems to strike a nice balance between usability in
the common cases (just set one option), expandability for more types of
files to install in future, and customizability of installation
directories.

This revision isn't completely working: standard and alternate
installations work fine, but there are still some kinks to work out of
customized installations.

irrelevant because this file is about to go away, but oh well.

have been checked in: was passing the PLAT environment variable as the
'plat' argument to 'new_compiler()'.

Added 'clean' to list of commands.

that broke parsing command-line options.  Instead call it in
'Command.find_peer()', which is why I added it to 'find_command_obj()'
in the first place.

  * improve help strings
  * warn if user supplies non-existing directories
  * don't try to 'remove_tree()' non-existing directories
  * try to remove the build_base after cleanup (but don't do or say
    anything if it fails -- this is just in case we made it empty)

use 'util.remove_tree()' instead of 'nuke_release_tree()'.

the Distutils 'clean' command.

option in the 'build_ext' command):
  * in ccompiler.py: 'gen_lib_options()' now takes 'runtime_library_dirs'
    parameter
  * in unixccompiler.py and msvccompiler.py: now pass
    'self.runtime_library_dirs' to 'gen_lib_options()', and define
    'runtime_library_dir_option()' (although in msvccompiler.py it
    blows up with a DistutilsPlatformError right now!)

'link_static_lib()'.

a static library (using lib.exe as found by '__init__()', hopefully through
registry entries pointing to DevStudio).

sure it's imported!  ;)

Re-wrap the docstrings on get_python_inc() and get_python_lib() to be
closer to the "normal" Python style.  See GvR's "style guide" on the
essays page (http://www.python.org/doc/essays/).

There should never be a space between a function name and the '(' that
opens the argument list (see the style guide again).

  the platform-neutral include dir by default and with Mac support.
Added 'get_python_lib()', inspired by 'get_python_inc()'.
Rewrote 'get_config_h_filename()' and 'get_makefile_filename()'
  in terms of 'get_python_inc()' and 'get_python_lib()'.
Changed '_init_nt()' and '_init_mac()' to use 'get_python_inc()' and
  'get_python_lib()' for directory names.

changed 'copy_file()' to use the native Mac file copy routine.

slashes, and put back together again using the local directory separator.

in a rather half-assed, but probably effective, way.

simpler implementation.

implement it (so far):
  * moved filename generation methods into CCompiler base class,
    driven by data supplied by implementation classes
  * moved a bunch of common code from UnixCCompiler to convenience
    methods in CCompiler
  * overhauled MSVCCompiler's compile/link methods to look and act
    as much as possible like UnixCCompiler's, in order to regularize
    both interface and behaviour (especially by using those new
    convenience methods)
