unhexlify() respectively).

commonly used functions to convert an arbitrary binary string into
a hexadecimal digit representation and back again.  These are often
(and often differently) implemented in Python.  Best to have one
common fast implementation.  Specifically,

binascii_hexlify(): a.k.a. b2a_hex() to return the hex representation
of binary data.

binascii_unhexlify(): a.k.a. a2b_hex() to do the inverse conversion
(hex digits to binary data).  The argument must have an even length,
and must contain only hex digits, otherwise a TypeError is raised.

after a brief conversation with TP.  First, the return values of the
PyString_* function calls should be checked for errors.  Second,
bit-manipulations should be used instead of division for spliting the
byte up into its 4 bit digits.

to this module to mirror sha's hexdigest() method.

PyErr_Restore().

This was a misleading bug -- the true "bug" was that hash(x) gave an error
return when x is an infinity.  Fixed that.  Added new Py_IS_INFINITY macro to
pyport.h.  Rearranged code to reduce growing duplication in hashing of float and
complex numbers, pushing Trent's earlier stab at that to a logical conclusion.
Fixed exceedingly rare bug where hashing of floats could return -1 even if there
wasn't an error (didn't waste time trying to construct a test case, it was simply
obvious from the code that it *could* happen).  Improved complex hash so that
hash(complex(x, y)) doesn't systematically equal hash(complex(y, x)) anymore.

The existing win32_error() function now returns the new(ish) WindowsError, ensuring we get correct error messages.

Fix the parent of WindowsError - both the comments in this source file, and the previous exceptions.py have WindowsError as a sub-class of OSError.

string literals has not been tested on an MS_WIN16 platform; the trailing
";" was inside the #ifndef MS_WIN16, which should cause an error (missing
semi-colon) when compiled with that symbol #defined.

and _PyString_Resize() fails on these shared strings.

Support for building the new w9xpopen.exe, which is used for reliable popen operation on Windows 9x.

Ensure the "proxied" command's return code bubbles back up.

This is an enhancement to a prior patch (100941) ...
[T]his patch removes the risk of deadlock waiting for the child previously present in certain cases. It adds tracking of all file handles returned from an os.popen* call and only waits for the child process, returning the exit code, on the closure of the final file handle to that child.

by Edward K. Ream <edream@users.sourceforge.net> about FILE* values and
incompatible C libraries in dynamically linked extensions.  It is not clear
(to me) how realistic the issue is, but it is better documented than not.

This closes SourceForge bug #111520.

  * use self.debug_print() for debug messages
  * uses now copy.copy() to copy lists
  * added 'shared_lib_extension=".dll"', ... , this is necessary if you
    want use the compiler class outside of the standard distutils build
    process.
  * changed result type of check_config_h() from int to string

  * changed some list.extend([...]) to list.append(...)
  * added '/g0' to compiler_options, so compiler doesn't

Properly end a comment block. It was terminated fine later but by a subsequent

talking about it. :)
