* correct shell utilities: params differ on mac, remove debug print,
+ correct a bug on windows
* Simplify the example, libz is also needed by libgd
* Framework function: simplify code gathering deps, collect_libs public
* Correct configure-make: get all lib files, also built with bazel
and pass them in LDFLAGS; correct the linking paths (add prefix)
* Make maximum line length for shell = 80
* Improve comments to the _InputFiles provider
* Allow execution on Windows, use utils_win.sh, copy instead of symlink
* Prepare for execution on Windows: set up environment, convert path
also rename TMPDIR since it can clash with widely used variable
