If you have such problems in the future, compile with -vut and the  
compiler will show where and what it searches, andwhy it refuses  
certain units or recompiles them.

In some cases, the compiler will want to immediately recompile  
previously compiled units:
a) if you use a unit that has in its interface section a procedure  
that is declared normally, but which is declared as "external".  
Solution: declare it immediately as "external" in the interface and  
remove the version in the implementation
b) if you have inline procedures in the interface of unit1 and a unit  
that uses unit1 is (indirectly) used in the implementation of unit1.  
Solution: compile everything with -Ur (= "create release units"; the  
compiler will never try to recompile such units afterwards, except if  
the interface section of a unit that it uses has been changed and this  
other unit has been recompiled).
