libiberty.a is being used because the tftpd (tftpd-hpa) package we  
are using uses xmalloc and the configure script that comes with that  
package determined that libiberty.a contains xmalloc.

I know that the cygwin getopt and libiberty getopt are different, but  
I was just wondering why there is a liberty directory in the cygwin src.

And finally for now, is there a way to use the cygwin version of  
getopt and not the libiberty version even if we need to link to  
libiberty?
