Thanks, Gerrit.  Both of your suggestions needed to be implemented for rsync
to compile cleanly.

Make error when getopt.h is not patched:

Administrator@AMC-OVREPORT /home/tfong/rsync2.4.6
$ make
gcc -I. -I. -O -c rsync.c -o rsync.o
In file included from /usr/include/unistd.h:7,
                 from rsync.h:87,
                 from rsync.c:23:
/usr/include/getopt.h:41: redefinition of `struct option'
/usr/include/getopt.h:56: conflicting types for `getopt_long'
lib/getopt.h:107: previous declaration of `getopt_long'
make: *** [rsync.o] Error 1

--> getopt.h version 1.3 was downloaded from Cygwin's CVS to replace
/usr/include/getopt.h

After getopt.h is patched to version 1.3, make produces this error:

Administrator@AMC-OVREPORT /home/tfong/rsync2.4.6
$ make
gcc -I. -I. -O -c rsync.c -o rsync.o
In file included from /usr/include/unistd.h:7,
                 from rsync.h:87,
                 from rsync.c:23:
/usr/include/getopt.h:41: redefinition of `struct option'
make: *** [rsync.o] Error 1

--> /usr/include/unistd.h was replaced with your patched version included in
this thread

The rsync 2.4.6 code produced peer reset errors when trying to obtain a
module listing.  This is corrected with patches supplied in rsync bug track
ID 3236 provided by Jonathan Kamens <jik@curl.com>.

Thanks again for your help!
Cheers,
\\TF.

/usr/include/getopt.h should not be included if you don't have 
the cygwin getopt_long version patched.

I got another error, because lib/getopt.h gets included and then
/usr/include/getopt/h gets included by unistd.h.

I have my unistd.h patched because it is causing trouble since lots 
of packages contains their own getopt.c / getopt.h like rsync, too.

Now Have you logged the output of configure?
There should be included this line: 
 checking for working getopt_long... no

Now if that is the case, lib/getopt.h gets included.

Here is how i patched /usr/include/unistd.h to get around 
this problem:

/* unistd.h for Cygwin. */

#ifndef _UNISTD_H_
#define _UNISTD_H_

# include <sys/unistd.h>
#if !defined(__GETOPT_H__) && !defined(_GETOPT_H)
# include <getopt.h>
#endif

#endif /* _UNISTD_H_ */


Ciao,

Gerrit
