Subject:	Q about unistd.h/getopt.h

I apologize if this has been asked, but I can't seem to access the mail
archives right now to check.  Anyway, I am building fetchmail,
and it mostly builds right out of the box, except for one small problem
which I noticed before but didn't pay attention to much.

It complains that fetchmail.c has an undefined variable
optind.  After looking around, and compiling the exact
same source on my debian box, I find out that getopt.h
is included in unistd.h, with the following code:

#ifdef  __USE_POSIX2
/* Get definitions and prototypes for functions to process the
   arguments in ARGV (ARGC of them, minus the program name) for
   options given in OPTS.  */
# define __need_getopt
# include <getopt.h>
#endif

and that nothing like this exists in cygwin.  

My debian machine is using 2.95.2-13 of gcc.  Is this a difference
in the versions of gcc, or an issue with the cygwin version of unistd.h?

Thanks
