* Can now test for basic blocks.
* Optimize inverted comparisions.
* Optimize unary_not followed by a conditional jump.
* Added a new opcode, NOP, to keep code size constant.
* Applied NOP to previous transformations where appropriate.

Note, the NOP would not be necessary if other functions were
added to re-target jump addresses and update the co_lnotab mapping.
That would yield slightly faster and cleaner bytecode at the
expense of optimizer simplicity and of keeping it decoupled
from the line-numbering structure.

  * UINT_MAX -> ULONG_MAX since we are dealing with longs
  * ParseTuple needs &int for 'i' and &long for 'l'
    There may be a better way to do this, but this works.

Remove "." in coverage output for lines with comments.
Silence complaints in coverage output about unexecuted docstrings.

Eliminate use of inspect module in favor of direct access to frame and
code objects.  We're in a trace function here:  Efficiency counts!

Remove unused code.  Reflow long lines.

Remove backwards compatibility for stored trace output from Zooko's
experiment to add calledfuncs to the pickled dict.

Move code to generate per-file coverage stats to a separate routine.

Replace use of parser module with call to compile.

- set the size of the DosQuerySysInfo buffer correctly; it was safe,
  but incorrect (allowing a 1 element overrun)

  * Fixed some long-hidden bugs revealed by the new PyUnit-based
    test suite (thanks to Johannes Gijsbers the new test suite,
    improved tests that caught the bugs, and the bug fixes).

  * Make store_true/store_false store True/False rather than 1/0.

I've applied a modified version of Greg Chapman's patch. I've included
the fixes without introducing the reorganization mentioned, for the sake
of stability. Also, the second fix mentioned in the patch don't fix the
mentioned problem anymore, because of the change introduced by patch
#720991 (by Greg as well). The new fix wasn't complicated though, and is
included as well.

As a note. It seems that there are other places that require the
"protection" of LASTMARK_SAVE()/LASTMARK_RESTORE(), and are just waiting
for someone to find how to break them. Particularly, I belive that every
recursion of SRE_MATCH() should be protected by these macros. I won't
do that right now since I'm not completely sure about this, and we don't
have much time for testing until the next release.

On cygwin, the setup.py script uses unixccompiler.py for compiling and linking
C extensions. The unixccompiler.py script assumes that executables do not get
special extensions, which makes sense for Unix.  However, on Cygwin,
executables get an .exe extension.

This causes a problem during the configuration step (python setup.py config),
in which some temporary executables may be generated. As unixccompiler.py does
not know about the .exe extension, distutils fails to clean up after itself: it
does not remove _configtest.exe but tries to remove _configtest instead.

The attached patch to unixccompiler.py sets the correct exe_extension for
cygwin by checking if sys.platform is 'cygwin'. With this patch, distutils
cleans up after itself correctly.
