But surely then the program would be broken anyway - in the case of a 
major version number bump. It is well known that major version changes 
mean two versions are NOT compatible.

What Martin is getting at is that by looking at the Object Pascal unit, 
one will then easily be able to see which major version of the library 
is supported by that header translation *.pp file. The linker will also 
complain and say that that specific library version is not install. 
That's a better error that some runtime crash or error about a API 
parameter that is now slightly different.

And just to be clear, by saying using the versioned library in the 
header translation unit, you will use the versioned library that only 
mentions the major version. eg:  'libgreat.so.1'    and not 
'libgreat.so.1.2.7'

Either way, I tried the latter as I mentioned, and it made no difference 
to FPC. Somewhere the version info was stripped and only the base name 
was passed to the linker.
