examples/Makefile: test on windows

- test the Makefile on windows
- skip DOS files on OS=Windows_NT
- add DLLEXT variable to discriminate .so versus .dll
- add export specifier in examples/threads/timer-lib/timer.bas
  allowing source to be compiled as static or shared (on windows)
  note: Makfile always compiles as shared
