Yes, that's a very good point.  The fewer VSIP_IMPL_HAVE_IPP/SAL/etc 
macros we have sprinlked all over the code, the better.  It will imporve 
readability and maintainability.

It may also prove necessary (or at least extremely useful) when we start 
to support platforms with different licensing rights.  For instance, if 
vendor X wants us to support their platform, but doesn't want that code 
in the open source release.  It will be much easier to leave out the 
files for platform X than it will be to excise a bunch of 
VSIP_IMPL_HAVE_X macros.
