Patrick Thomson 39bfcdf595 Fix build with MinGW tooling. (#514)
Courtesy of @Eli-Zaretskii, these fixes should unblock people from
building tree-sitter with MinGW.

I don't think this is an unreasonable maintenance burden, especially
given the Emacs project's interest in using tree-sitter, but
@maxbrunsfeld gets the final call.
