=head1 DESCRIPTION
=head2 AIX Dynaloading
-The AIX dynaloading now uses the native dlopen interface of AIX,
-(given the AIX is recent enough) instead of the old emulated interface.
-This will probably break backward compatibility with compiled modules.
+The AIX dynaloading now uses in AIX releases 4.3 and newer the native
+dlopen interface of AIX instead of the old emulated interface. This
+change will probably break backward compatibility with compiled
+modules. The change was made to make Perl more compliant with other
+applications like modperl which are using the AIX native interface.
=head2 Socket Extension Dynamic in VMS
old code that used floating point numbers even for integer constants),
and slightly faster, you might want to consider regenerating your
extension code (the new scheme makes regenerating easy).
+L<h2xs> now also supports C trigraphs.

-AIX should now work better with gcc. Also longdouble support in AIX
-should be better now. See L<perlaix>.
+AIX should now work better with gcc, threads, and 64-bitness. Also the
+long doubles support in AIX should be better now. See L<perlaix>.

Several MacOS (Classic) portability patches have been applied. We
hope to get a fully working port by 5.8.0. (The remaining problems
relate to the changed IO model of Perl.) See L<perlmacos>.
Examples include any platform using sfio, and Compaq/Tandem's NonStop-UX.
The failing platforms do not comply with the ANSI C Standard, line
19ff on page 134 of ANSI X3.159 1989 to be exact. (They produce
-something else than "1" and "-1" when formatting 0.6 and -0.6 using
+something other than "1" and "-1" when formatting 0.6 and -0.6 using
the printf format "%.0f", most often they produce "0" and "-0".)
