+A warning will be produced when you create more than one alias to the same
+value. This may be worked around in a backwards compatible way by creating
+multiple defines which resolve to the same value, or with a modern version
+of ExtUtils::ParseXS you can use a symbolic alias, which are denoted with
+a C<< => >> instead of a C<< = >>. For instance you could change the above
+so that the alias section looked like this:
+
+ ALIAS:
+ FOO::gettime = 1
+ BAR::getit = 2
+ BAZ::gettime => FOO::gettime
+
+this would have the same effect as this:
+
+ ALIAS:
+ FOO::gettime = 1
+ BAR::getit = 2
+ BAZ::gettime = 1
+
+except that the latter will produce warnings during the build process. A
+mechanism that would work in a backwards compatible way with older
+versions of our tool chain would be to do this:
+
+ #define FOO_GETTIME 1
+ #define BAR_GETIT 2
+ #define BAZ_GETTIME 1
+
+ bool_t
+ rpcb_gettime(host,timep)

+(also known as C<xsubpp>) 3.50
+
+=head1 AUTHOR DIAGNOSTICS
+
+As of version 3.49 certain warnings are disabled by default. While developing
+you can set C<$ENV{AUTHOR_WARNINGS}> to true in your environment or in your
+Makefile.PL, or set C<$ExtUtils::ParseXS::AUTHOR_WARNINGS> to true via code, or
+pass C<< author_warnings=>1 >> into process_file() explicitly. Currently this will
+enable stricter alias checking but more warnings might be added in the future.
+The kind of warnings this will enable are only helpful to the author of the XS
+file, and the diagnostics produced will not include installation specific
+details so they are only useful to the maintainer of the XS code itself.
