[ECOS]Compiler erros with cygwin

[Masashi Ichikawa]

Hello, 

Recently, I started to build a package for our custom board.
To my trouble, when I try to install the package, config tool
reports the following error.

  Command Execution Error
  extracting pkgadd.db:
  /usr/bin/tar: Skipping to next header
  /usr/bin/tar: Error exit delayed from previous errors.

I can't guess the cause of this error. Does anybody have any 
advice? Any hints are welcome.

Thanks,
