Re: [Bug-tar] compiling tar cvs using mingw

[Gerry Reno]

Paul,
  For the SIGPIPE error:  SIGPIPE is defined in the cygwin env (unix
emulation) but not the mingw env (native windows runtime).  Does this
either means no rmt access with mingw or some ifdef code necessary?

  This is really the only error that I cannot get by without major
hack.  For now I just put dummy value but it is useless for mingw.

  So here is the first result at creating tar executable under mingw:

  Functions are shown as undefined even though they are declared in the
same module?  Is this related to defining MSDOS?  Investigating...
