This involves changing the zlib build process to build zlib itself from sources, then use that library.  Also updated are the comments to reflect the new official home of zlib, and add Windows specific notes regarding the build process.

"Partial" as the code uses sys.prefix in an attempt to locate 'w9xpopen.exe', but sys.prefix is not set if Python can't find it itself.  So this _still_ fails in Pythonwin, but I am committing the patch for 2 reasons:
* Embedded apps that set sys.prefix or use PYTHONHOME will work
* The exception raised on failure to find the executable is far more obvious

Removed illegal redefinition of REPR macro; kept the one with the
argument name that isn't too easy to confuse with zero <wink>.

Tested for not breaking builds on Linux.

recently fixed bug, but it checked for the wrong answer.

imports.  It checks for them now.

reference manual but not checked: Names bound by import statemants may
not occur in global statements in the same scope. The from ... import *
form may only occur in a module scope.

I guess these changes could break code, but the reference manual
warned about them.

Several other small changes

If a variable is declared global in the nearest enclosing scope of a
free variable, then treat it is a global in the nested scope too.

Get rid of com_mangle and symtable_mangle functions and call mangle
directly.

If errors occur during symtable table creation, return -1 from
symtable_build().

Do not increment st_errors in assignment to lambda, because exception
is not set.

Add extra argument to symtable_assign(); the argument, flag, is ORed
with DEF_LOCAL for each symtable_add_def() call.

typedef, and at least one compiler choked on this.

(SF patch #103457, by bquinlan)

This change eliminates an extra malloc/free when a frame with free
variables is created.  Any cell vars or free vars are stored in
f_localsplus after the locals and before the stack.

eval_code2() fills in the appropriate values after handling
initialization of locals.

To track the size the frame has an f_size member that tracks the total
size of f_localsplus. It used to be implicitly f_nlocals + f_stacksize.

Don't call OpenDeskAcc() and AppendResMenu() on Carbon.

Removed device from the list of Qd incompatibilities. It should be there, but causes too many false positives.

Accessor functions for regions and such expect an existing region as parameter. Fixed for grafport attribute access.
Got GetPortBitMapForCopyBits() and port.portBits to work.

Added generators for EnableMenuItem and CheckMenuItem (which have Mac in front of their name in the include files).

Replace {Enable,Disable,Check}Item with their carbon-compatible equivalents {Enable,Disable,Check}MenuItem.
