subset of Win32 ShellExecute's functionality.  Guido wants this because
IDLE's Help -> Docs function currently crashes his machine because of a
conflict between his version of Norton AntiVirus (6.10.20) and MS's
_popen.  Docs for startfile are being mailed to Fred (or just read the
docstring -- it tells the whole story).
Changed webbrowser.py to use os.startfile instead of os.popen on Windows.
Changed IDLE's EditorWindow.py to pass an absolute path for the docs
(hardcoding ShellExecute's "directory" arg to "." as used to be done let
IDLE work, but made the startfile command exceedingly obscure for other
uses -- the MS docs are terrible, of course, & still not sure I
understand it).
Note that Windows Python must link with shell32.lib now!  That's where
ShellExecute lives.

glob.glob("k:*py") (i.e., a raw drive letter + colon at the start) were
using the root of the drive rather than the expected Windows behavior
of using the drive's "current directory".

This should match the situation in the 1.6b1 tree.

implementation.  You don't want to know.  I've asked Guido to give this
a critical review (we agreed on the approach, but the implementation
proved more ... interesting ... than anticipated).  This will almost
certainly be the highlight of Mark Hammond's day <wink>.

Minor updates for BeOS R5.

Use of OSError in test.test_fork1 changed to TestSkipped, with corresponding
change in BeOS/README (by Fred).

This closes SourceForge patch #100978.

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

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.

for systems that are missing those declarations from system include files.
Start by moving a pointy-haired ones from their previous locations to the
new section.

(The gethostname() one, for instance, breaks on several systems, because
some define it as (char *, size_t) and some as (char *, int).)

I purposely decided not to include the summary of used #defines like Tim did
in the first section of pyport.h. In my opinion, the number of #defines
likedly to be used by this section would make such an overview unwieldy. I
would suggest documenting the non-obvious ones, though.

possible.

and a couple of functions that were missed in the previous batches. Not
terribly tested, but very carefully scrutinized, three times.

All these were found by the little findkrc.py that I posted to python-dev,
which means there might be more lurking. Cases such as this:

long
func(a, b)
	long a;
	long b; /* flagword */
{

and other cases where the last ; in the argument list isn't followed by a
newline and an opening curly bracket. Regexps to catch all are welcome, of
course ;)

comments, docstrings or error messages. I fixed two minor things in
test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't").

There is a minor style issue involved: Guido seems to have preferred English
grammar (behaviour, honour) in a couple places. This patch changes that to
American, which is the more prominent style in the source. I prefer English
myself, so if English is preferred, I'd be happy to supply a patch myself ;)

works.

In posixmodule.c:posix_fork, the function PyOS_AfterFork is called for
both the parent and the child, despite the docs stating that it should
be called in the new (child) process.

This causes problems in the parent since the forking thread becomes the
main thread according to the signal module.

Calling PyOS_AfterFork() only in the child fixes this.  Changed for both
fork() and forkpty().
