=head2 Compiling Perl 5 on AIX
-For information on compilers on older versions of AIX, see L<Compiling
+For information on compilers on older versions of AIX, see L</Compiling
Perl 5 on older AIX versions up to 4.3.3>.
When compiling Perl, you must use an ANSI C compiler. AIX does not ship
If you plan to link Perl to any module that requires thread-support,
like DBD::Oracle, it is better to use the _r version of the compiler.
This will not build a threaded Perl, but a thread-enabled Perl. See
-also L<Threaded Perl> later on.
+also L</Threaded Perl> later on.
As of writing (2010-09) only the I<IBM XL C for AIX> or I<IBM XL C/C++
for AIX> compiler is supported by IBM on AIX 5L/6.1/7.1.

Successfully tested means that all "make test" runs finish with a
result of 100% OK. All tests were conducted with -Duseshrplib set.
The -1 removes this limit. If the "make test" fails please change
your /etc/security/limits as stated above.
+=head2 Long doubles
+
+IBM calls its implementation of long doubles 128-bit, but it is not
+the IEEE 128-bit ("quadruple precision") which would give 116 bit of
+mantissa (nor it is implemented in hardware), instead it's a special
+software implementation called "double-double", which gives 106 bits
+of mantissa.
+
+There seem to be various problems in this long double implementation.
+If Configure detects this brokenness, it will disable the long double support.
+This can be overridden with explicit C<-Duselongdouble> (or C<-Dusemorebits>,
+which enables both long doubles and 64 bit integers). If you decide to
+enable long doubles, for most of the broken things Perl has implemented
+workarounds, but the handling of the special values infinity and NaN
+remains badly broken: for example infinity plus zero results in NaN.

+=head2 Compiling Perl 5 on AIX 7.1.0
+
+A regression in AIX 7 causes a failure in make test in Time::Piece during
+daylight savings time. APAR IV16514 provides the fix for this. A quick
+test to see if it's required, assuming it is currently daylight savings
+in Eastern Time, would be to run C< TZ=EST5 date +%Z >. This will come
+back with C<EST> normally, but nothing if you have the problem.

=head2 Compiling Perl 5 on older AIX versions up to 4.3.3
Due to the fact that AIX 4.3.3 reached end-of-service in December 31,
cumulative.
