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, 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".)
