As of 2.4.7, rsync uses Eric Troan's popt option-parsing library. A
cut-down copy of release 1.5 is included in the rsync distribution,

the --with-included-popt option is passed to ./configure.

+If you configure using --enable-maintainer-mode, then rsync will try
+to pop up an xterm on DISPLAY=:0 if it crashes. You might find this

+RPM NOTES
+---------
+
+Under packaging you will find .spec files for several distributions.
+The .spec file in packaging/lsb can be used for Linux systems that
+adhere to the Linux Standards Base (e.g., RedHat and others).

+HP-UX NOTES
+-----------
+
+The HP-UX 10.10 "bundled" C compiler seems not to be able to cope with
+ANSI C. You may see this error message in config.log if ./configure
+fails:
+
+ (Bundled) cc: "configure", line 2162: error 1705: Function prototypes are an ANSI feature.
+
+Install gcc or HP's "ANSI/C Compiler".

+MAC OSX NOTES
+-------------
+
+Mac OS X (Darwin) seems to have an IPv6 stack, but it does not
+completely implement the "New Sockets" API.
+
+<http://www.ipv6.org/impl/mac.html> says that Apple do not support
+IPv6 yet. If your build fails, try again with --disable-ipv6.
+
+IBM AIX NOTES
+-------------
+
+IBM AIX has a largefile problem with mkstemp. See IBM PR-51921.
+The workaround is to append the below to config.h
+ #ifdef _LARGE_FILES
+ #undef HAVE_SECURE_MKSTEMP
+ #endif
