But the glueing together destroys any modularization they had going on, making the code way harder for anyone else to understand and read. The "typical" solution to that very valid problem is to use the preprocessor, i.e. create a "ph7-master.c" file that simply includes all the real C files. The comparative overhead of should be negligble, but then the modularization survives.
