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.

Not really.  A DLL is unlike a regular library, and neither
cygwin1.dll nor the MS dlls exist in non-dll form.

No.

Statically linking programs??

[Mark Paulus]

I was looking through the FAQ, and I see about an option to 
build binaries that link either the cygwin or the Micro$oft
dlls.  However, I do not see an option to build statically linked
binaries that require no dlls.  Is this a possibility??

(-static doesn't seem to have any effect:
man gcc:
       -static
              On  systems that support dynamic linking, this pre-
              vents linking with the shared libraries.  On  other
              systems, this option has no effect.
