Not under windows.  All windows programs require a runtime library of
some sort (like "glibc" on linux).  On the windows platform, all of the
available runtime libraries are dynamic libs (dlls).  This includes:
  msvcrt.dll  (microsoft runtime)
  crt.dll     (older microsoft runtime)
  cygwin1.dll (cygwin runtime)

Incorrect.  "-static" causes the linker to *prefer* static libs over
dynamic libs, but if there is only a dynamic lib then the linker goes
ahead and uses it rather than bail out and fail.  In the case of runtime
libraries, there are only dll's -- so you will always dynamically link
to one of the runtimes.
