it so BCPPCompiler actually works, so I'm provisionally accepting it
-- ugly and working is better than not working!  Major changes:
  - normalize paths (apparently BC++ doesn't like slashes)
  - overhauled how we search for and specify libraries on the linker
    command-line
  - hacked up 'find_library_file()' so it knows about "debug" library
    naming convention as well as "bcpp_xxx.lib" -- the question is,
    is this a well-established and sensible convention?
Also:
  - change to use 'util.write_file()' to write the .def file

'export_symbols' can be None (not sure this is a good idea: it's inconsistent
  with every other instance attribute of Extension).

the linker leaves the (temporary) .lib file in the temporary dir.  (Moved
from 'msvc_prelink_hack()' method in build_ext.py.)

  - 'export_symbol_file' (and corresponding 'def_file' in the old
    "build info" dict) are gone; warn if we see 'def_file' in the
    dict
  - the MSVC "pre-link hack" is gone -- all that stuff is now handled
    elsewhere (eg. by using 'export_symbols', etc.)
  - add 'get_export_symbols()' and 'get_libraries()' methods -- needed
    because on Windows, both of those things are a tad more complicated
    than fetching them from the Extension instance

  mere warnings.
Call 'findall()' on our FileList object before we start using it seriously.

Added 'remove_duplicates()'.
Simplified constructor: no longer take 'files' or 'allfiles' as args,
  and no longer have 'dir' attribute at all.
Added 'set_allfiles()' and 'findall()' so the client does have a
  way to set the list of all files.
Changed 'include_pattern()' to use the 'findall()' method instead of
  the external function.  (Of course, the method is just a trivial
  wrapper around the function.)

instance instead of a list of filenames.  Simplifies the "sdist" command
only a bit, but should allow greater simplification of FileList.

which I renamed to FileList: remove all the file-list-generation code from
the sdist command and adapt it to use the new FileList class instead.

Other cosmetic/doc/comment tweaks.

'_parse_template_line()'.

Indentation/whitspace fixes.

the filesystem, and filtering the list by applying various patterns.

Initial revision (almost) as supplied in a patch by Rene Liebscher; I
just renamed the class from Template to FileList, and the module
accordingly.

Comment tweak.

'shared_library_filename()'.

  temporary directory ('bdist_base').
Added --dist-dir option to control where the executable is put.

they place their output files.

defaults to 'dist' (ie. no longer in the distribution root).

This'll work fine with 2.0 or 1.5.2, but is less than ideal for
1.6a1/a2.  But the code to accomodate 1.6a1/a2 was released with
Distutils 0.9, so it can go away now.

misc/install.c, still needs to be updated, and it looks like a non-trivial
change.

otherwise just generate an '/export:' option.

fail do we try for win32api/win32con.  If *those* both fail, then we don't
have registry access.  Phew!

More reformatting by me.
Also added some editorial comments.

we can run "sdist" on a distribution with old-style extension structures
even if we haven't built it yet.  Bug spotted by Harry Gebel.

Changed 'prune_file_list()' so it also prunes out RCS and CVS directories.
Added 'is_regex' parameter to 'select_pattern()', 'exclude_pattern()',
  and 'translate_pattern()', so that you don't have to be constrained
  by the simple shell-glob-like pattern language, and can escape into
  full-blown regexes when needed.  Currently this is only available
  in code -- it's not exposed in the manifest template mini-language.
Added 'prune' option (controlled by --prune and --no-prune) to determine
  whether we call 'prune_file_list()' or not -- it's true by default.
Fixed 'negative_opt' -- it was misnamed and not being seen by dist.py.
Added --no-defaults to the option table, so it's seen by FancyGetopt.

'link_shared_object()'.

methods (but not 'link_executable()', hmmm).  Currently only used by
BCPPCompiler; it's a dummy parameter for UnixCCompiler and MSVCCompiler.

Also added 'bcpp' to compiler table used by 'new_compiler()'.
