For GCC 'make clean' isn't as effective as removing everything, it doesn't remove Makefiles for starters. > and the source directory Unnecessary, that's the major benefit of the build directory being separate from the source directory, the source directory is never touched (and could even be read-only). (However if you have previously built in the source directory then it is worth deleting ti and starting again, but as long as you always build in a separate build dir the sources will stay pristine.)
