Yes, you need to switch to Python 3 :-)

incompatible and there's no other way to work around this
other than to make use of the errorhandler conditionally

And please add unit tests...
I'm thinking on this. I plan to write tests for all my last changes about
surrogates.

I always consider Windows as a special case because Windows uses unicode
internally. Byte string are converted quickly to unicode using the current
locale.
My patch was for UNIX/BSD which uses byte

load_library() uses LoadLibraryW() which use a WCHAR*. To support bytes, we can
use LoadLibraryA() and TCHAR*.

PEP 277 explicitly states that unicode strings should be passed to
wide-character functions, whereas byte strings use standard functions.
This is done in posixmodule.c, for example.
The current locale is a moving thing.

I only fixed UNIX/BSD versions of subprocess/ctypes.dlopen() because it's not
possible to open some files with an undecodable filename. On Windows, the file
system and Python3 use Unicode, and so there is no such corner case.

yes, except that TCHAR* depends on compilation settings (it resolves to wchar_t
when UNICODE is #defined); simply use char*.

Odd, works for me on 10.4, 10.5, and 10.6 (but I have never tried running under
buildbot, if that is what is happening here).
For 10.4 with its most-recent Xcode installed:
$ /usr/bin/ld -v
Apple Computer, Inc. version cctools-622.9~2
$ /usr/bin/gcc

Some notes about the patch:
- NEWS blurbs generally appear antichronologically, that is newest first :-)
- you don't have to mention that The 3.2 changes mentioned above are included
in 2.7
- the part of the PyArg_ParseTupleAndKeywords string

Also, _POSIX_SEMAPHORES must be defined to be greater than 200112L. If it
isn't, then it isn't supported.
