In the 90s I used to add the C preprocessor to other languages 
which lacked efficient constant definition (i.e. compile time 
constructs). AutoLISP, the LISP dialect used to write application 
in AutoCAD. There were nearly a 100 of small programs in 
different files and throughout the whole project there were a lot 
repetitions that could not be factorized with AutoCAD means. 
Include, define and ifdef allowed to do things, that were very 
difficult to do at that time (it was on AutoCAD v9.0 which had 
only 64K memory for the LISP code).
I also added the C preprocessor to the DBASE III and the 
compatible MS-DOS based Foxbase.
