Ah- I hadn't thought of := on the command line :-) OK, situation as of 
0.9.28.3 + 2.4.0 appears to be that the compiler ignores = (i.e. stores 
the whole thing as a shell variable) but breaks on := (i.e. stores the 
left-hand part only), however it only defines the shell variable, it 
doesn't assign it a value. Much the same for 27705 + 2.4.2-rc1 (I'm not 
complaining, only summarising).

Since := is significant in the -d option I wonder whether fpc -h should 
be updated.

However the whole thing is slightly academic since Mattias has 
contributed his

which looks like it will handle the project name issue perfectly.
