Yes, but you have the burden of automake (automatically remake if files
changed), so you have to check if all source files (.pas and .inc) and
dependant units are in sync.

The fact that typical (Borland) Pascal compilers compile a whole string of
units in one go helps though. The dependant units are often already loaded
into mem.

C usually puts that burden on make.
