- update urls
- sync examples makefiles with main ones
- remove line ending space

This fixes using a multi-target mingw distro to build curl .dll for the
non-default target.

It would otherwise cause problems when running tests after 1801 etc.

... as it was previouly undocumented what the pointer was.
