This probably means that you have an old version of the runtime headers
installed. Since you give no information on what runtime version you're
using, where you got it, and so on, I can only suggest that you get a
newer one from my site:

  ftp://ftp.xraylith.wisc.edu/pub/khan/gnu-win32/mingw32/runtime/

the 1999-07-31 is the one I distribute with gcc-2.95 binaries and is 
considered stable. My next 'stable' update will probably be in about
2 weeks from now.
