Commit 2cb4b6534fbcbe600ecf3db95ba19e4525c8d4b8
2015-08-05T10:19:06
Fix duplicate basenames to support older VS With Visual Studio versions 2008 and older they ignore the full path to files and only check the basename of the file to find a collision. Additionally, having duplicate basenames can break other build tools like GYP. This fixes https://github.com/libgit2/libgit2/issues/3356
