This is normal behaviour, contrary to languages that don't have any scoping
what..so..ever.

1. Indeed, check.

2. Make sure your makefile passes the define to each unit.


Seriously, this is for a reason. With the FPC (and any other Wirthian
(pascal-like)) language with a unit/module system, you can't predict
the exact way the different files/units are compiled, so therefore
defines are restricted to that compilationunit. 

This is the downside of an actual generally postive feature ( the compile
figures the right compilation order, and is generally right about it), with
the above 2 workarounds as an alternative.
