Right. But the proposal, if implemented, introduces one case where 
either the fpc binary or the ppcxxx compiler cannot be located because 
their paths depend on the FPCVER macro. In that case, the FPCVER macro 
needs to be manually set/selected in the IDE to allow the paths to 
resolve correctly. And as a sanity check, the FPC binary can then be 
queried for the version, and that version is compared with the 'forced' 
FPCVER macro.

If this is somehow convoluted (for this specific case), then instead of 
having the paths depend on FPCVER, they could depend on some user 
defined macro (e.g. USERFPCVER or XYZ) provided the user is able to set 
that macro in the IDE options via some selector.
