develop branch does not compile on Windows

[archerian]

Several issues prevent a successful build on Windows.. some of which are

strncasecmp not available (use_strnicmp)
closedir not available (use FindClose)
undeclared local variables in config__get_dir_files (len, i, dh/fh)
SigThreadProc function might be missing a closing brace, and undeclared before use at CreateThread

Thanks we'll take a look. For completeness, what are you using to build with?

VS 2017 (15.15.1)

This commit fixes the build with VS 2015. It disables static libraries by default for the moment.

Thanks for reporting it.
