Rather than describing what you did, copy and paste a shell transcript showing
the commands and output from you listing the source code, compiling and running
it, a long listing of the directory contents, then run
"cygcheck -hrsv > cygcheck.out"
and attach the output as a text file to a post to this list, as explained below
under Problem reports: http://cygwin.com/problems.html.
