Summary: compileall doesn't notice syntax errors

Initial Comment:
compileall.py returns an exit code to indicate the
success or failure of compilation.  This feature was
added in compileall.py revision 1.7 in response to
distutils message 
http://mail.python.org/pipermail/distutils-sig/1999-March/000201.html

This is not as useful as it looks because a prior
change to py_compile.py (revision 1.13) catches syntax
errors, hiding them completely from compileall.py, so
compileall.py can't report the failure to its caller.

Reopening this bug as it's entirely unclear why the
py_compile.py change wasn't checked in. This has resulted in
a new bug, #653301.

I've attached a patch that's updated for current CVS (rev.
1.23 of py_compile.py).

Since py_compile.py is crucial to the install process I'd
rather have someone else make the decision to check this in
or not.

I don't see how this can be fixed in compileall.py since the
problem 
is with py_compile.py.  py_compile.compile (up to and
including the 
latest version I see in CVS, revision 1.18) only ever
returns None, 
so the code in compileall.py revision 1.19 that says:
   ok = py_compile.compile(fullname, None, dfile)
and 
   if ok == 0:
can't possibly work.
Caveat: this comment based on reading code, not running it.

Fixed in rev 1.9 of compileall.py.  Note that this fix
causes a bunch of changes to the test suite, so that files
containing syntaxerrors are not compiled by compileall.

I think this is easy enough to fix, but I don't know what
unintended side-effects the fix will have.
