Agreed, but it will compile and writing an adaptor layer to let it call a 
modern library is probably a lot easier then adapting the old source, 
particularly if its a large, badly documented program. 

But with Python and other languages whose compilers aren't backward 
compatible, you don't have the option of writing an adaptor layer. 
Instead, you're forced to review/rewrite your source code every time the 
language spec changes, which is typically every 2 to 5 years for most 
languages.
