Thanks for the responses:

The `gtopt.h' "is part of the GNU C Library"
and the one distributed by cygwin is copytighted by
"The Regents of the University of California".

Is there a conventional way to avoid the reading of the first one
distributed by Cygwin in view to read only the distributed by `tetex' ?

Is it dangerous to define "__GETOPT_H__" somewhere to do that ?

Thanks in advance,
Jerome BENOIT
