I certainly don't need to be right here ;-) but my thought was that if
Lazarus wanted to cater for both standard installations (releases) and
non-standard ones (allowing users to configure them inside Lazarus rather
than expecting that Lazarus should detect them automatically, of course)
as suggested by Mattias in his earlier e-mail, using -Xp would be a more
generic solution.

That obviously does not imply that -V shouldn't be used with fpc for other
use cases, it's just that it may not fit the Lazarus need completely (as
far as I understood Mattias correctly, of course).
