There was a problem hiding this comment.
I think we should just use this function everywhere. I don't see any reason we should need the alternate code path.
Checking Windows 32bit build https://julialang-s3.julialang.org/bin/winnt/x86/0.6/julia-0.6.1-win32.exe , libgit2.dll does use `_chsize_c`, so both 32bit and 64bit should be able to use `_chsize_c`.

Alternate code path removed. |
