+=item warning: dead part of constant expression is nonconstant

+If you are using the Sun Studio 10 compilers ('cc -V' reports "Sun C 5.7") you
+may see lots of these errors while building perl.  This is an erroneous warning
+from the compiler, if you are interested in the details the Sun bug id is
+6344975.  The warnings can safely be ignored, but if they bother you they may
+be suppressed by adding "-Accflags=-erroff=E_DEAD_NONCONST" to your Configure
+command-line.  Note however that earlier versions of the compiler don't have the
+ability to report this warning and will complain about a bad message tag if you
+specify that you want the compiler to suppress the warning.  Note also that the
+erroff option embedded into Config.pm and will be used for building any XSUB
+modules post-install.
