Revision 960b9b7a2f6e9b4f0e6b692d604c53b3fd2f5d1c authored by Jeffrey Yasskin on 28 February 2008, 04:45:36 UTC, committed by Jeffrey Yasskin on 28 February 2008, 04:45:36 UTC 
Move abc._Abstract into object by adding a new flag Py_TPFLAGS_IS_ABSTRACT,
 
which forbids constructing types that have it set. The effect is to speed

  ./python.exe -m timeit -s 'import abc' -s 'class Foo(object): __metaclass__ = abc.ABCMeta' 'Foo()'

up from 2.5us to 0.201us. This fixes issue 1762.

grammar.mak 
# This manages to rebuild graminit.{h, c} under MSVC 6 (Windows), via
#
#     nmake /f grammar.mak
#
# You may also need to copy python23.dll into this directory, or get
# it on your search path.
#
# The intermediate files can be nuked afterwards:
#
#     nmake /f grammar.mak clean
#
# I don't understand the maze of preprocessor #define's on Windows, and
# as a result this requires linking with python23.lib, so it's of no use
# for bootstrapping (the cause appears to be a useless-- in this
# particular case --pragma in PC\pyconfig.h, which demands that
# python23.lib get linked in).
