This is why I think a __BORLANDC__LATEST could be used.  Define it as 
0x564 now, and if __BORLANDC__ > __BORLANDC__LATEST, then error to show 
that a new version has been released.  Then, either __BORLANDC__LATEST 
could just be updated to include the new version, or specific patches 
could be then given specific version numbers if the latest patch has 
fixed the problem.

Another way is to try and remove completely checks against compiler 
versions in code and put all this checks in compiler config header, then 
when new versions come out, you just update the list for the new version 
in one place.  This may be a better solution but will mean a lot of 
#defines in the compiler config headers for non-conforming compilers.
