+the AIX Toolbox which is shipped with AIX.
=head2 Supported Compilers
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.

+
+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.
-As of writing (2008-11) only the IBM XL C for AIX or XL C/C++ for AIX
-compiler is supported by IBM on AIX 5L/6.1.
+The following compiler versions are currently supported by IBM:
-The following compiler versions are supported by IBM:
+ IBM XL C and IBM XL C/C++ V8, V9, V10, V11

+The XL C for AIX is integrated in the XL C/C++ for AIX compiler and
+therefore also supported.
-The XL C for AIX is integrated in the XL C/C++ for AIX compiler.
+If you choose XL C/C++ V9 you need APAR IZ35785 installed

+to an optimization bug. You can circumvent this problem by
+adding -qipa to the optimization flags (-Doptimize='-O -qipa').

+=head2 Incompatibility with AIX Toolbox lib gdbm
+
+If the AIX Toolbox version of lib gdbm < 1.8.3-5 is installed on your
+system then Perl will not work. This library contains the header files
+/opt/freeware/include/gdbm/dbm.h|ndbm.h which conflict with the AIX
+system versions. The lib gdbm will be automatically removed from the
+wanted libraries if the presence of one of these two header files is
+detected. If you want to build Perl with GDBM support then please install
+at least gdbm-devel-1.8.3-5 (or higher).

-called runtime linking mode instead of the emulated interface that was
-used in Perl releases 5.6.1 and earlier or, for AIX releases 4.2 and
-earlier. This change does break backward compatibility with compiled
-modules from earlier Perl releases. The change was made to make Perl
-more compliant with other applications like Apache/mod_perl which are
-using the AIX native interface. This change also enables the use of

It is highly recommended to use the new interface.

If your AIX system is installed with 64-bit support, you can expect 64-bit
configurations to work. If you want to use 64-bit Perl on AIX 6.1

With the default setting the size is limited to 128MB.
-The -1 removes this limit.
+The -1 removes this limit. If the "make test" fails please change

+=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.
-=head2 Recommended Options AIX 5.1/5.2/5.3 and 6.1 (threaded/32-bit)
+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 overriden 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 Recommended Options AIX 5.1/5.2/5.3/6.1 and 7.1 (threaded/32-bit)
