The problem doesn't affect you directly.
The issue is that we need a way to distingish between 32bit and 64bit
because we merge arch/${platform}/inlcude/ast/ includes from 32bit and
64bit builds via "/usr/bin/diff -D<symbol>". The problem is that we
can't use |_LP64| for <symbol> since the Sun Workshop/Forte/Studio
compilers do not set |_LP64| (gcc set it, e.g.
-- snip --
$ (touch foo.h; /usr/sfw/bin/cpp -m64 -dM foo.h) | fgrep _LP64
#define __LP64__ 1
#define _LP64 1
-- snip --
) and "injecting" a |#include <sys/isa_defs.h>| will fork() the includes
in a completely unpredictable manner (I've tried that - the sources
compile and the code doesn't pass the test suite anymore (and I really
don't have the time to figure out why it breaks somewhere in the ~~1000
source files we have... that's more a job for Mr. Sisyphus)).
