resolve compiler error in visual c++.
Created by: kochelmonster
This pull request contains the changes discussed in #98 (closed). Also if it is perfect standard c++, the fact is: msvc does not compile it, and I don't assume Microsoft will change their compiler.
For those who are interested: I was able to compile pyicu with the following conda packages:
- icu=64.2=he025d50_1
- vs2017_win-64=19.16.27032.1=hb4161e2_0
