I believe that many problems of this kind could be solved at the root if 
the fpc error message was not as misleading as it is currently.

The error message lets you believe that it didn't find an Expr.pas or an 
Expr.ppu, while the actual problem was that it found an 
invalid/conflicting .ppu.

Two different messages, one telling "can't find unit xxx" and another 
telling "unit xxx invalid ppu" would save a lot of troubles and lead you 
to quickly find the reason.

Shouldn't we ask fpc to provide better error messages for this case?
