Differences like that usually point out a poor interaction between the files and the make process. For example, if you provide the compiler with a list of files, you may only have to load the compiler once but you can compile many modules. If you use make and load the compiler many times, it will take much longer to build a system. We had one program that the computer center manager tried to build and after 7 hours, he killed the job. It was only half way done. I suggested Microsoft's Power Fortran which loaded once and compiled many. The MS Fortran compiler completed the build in 2 minutes. It took me around 30 minutes to figure out that it had compiled everything. MS Power Fortran went on to be DEC's Fortran for PCs and I don't know what it called now. CPU speeds and HD speeds were much slower when this happened.
