Fail to build on Windows and Python 2.7

[pombredanne]

In trying to build a Windows wheel on Appeyor, I got this error: https://ci.appveyor.com/project/pombreda/thirdparty/build/job/0p8m9ou4or8q8iru#L132

@pombredanne I can't be able to see the error you are mentioning, can you provide me with more information? When I click on link, I see the latest build and that one seems to be passing (I believe you are using cdifflib there, not edlib, so that is probably why).

@Martinsos thank you for the quick reply and sorry for the incorrect link. Here it is corrected: https://ci.appveyor.com/project/pombreda/thirdparty/builds/24286191/job/0p8m9ou4or8q8iru#L130

This is a "classic" stdint Windows issue: fatal error C1083: Cannot open include file: 'stdint.h': No such file or directory

FWIW a resolution example from @WojciechMula is to use msinttypes by @chemeris https://github.com/chemeris/msinttypes

See https://github.com/WojciechMula/pyahocorasick/tree/master/msinttypes https://github.com/WojciechMula/pyahocorasick/blob/82fede70c509d35ea268031f24c4a457b738e0e2/windows.h and search msinttypes for other places where this is referenced in that repo to build a proper wheel.

The full error trace is:

%PYTHON%\python.exe -m pip wheel edlib --wheel-dir=wheels
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.
