That's indeed not FPC starting executables, that's Lazarus invoking "make" (which in turn invokes tons of other stuff).

make indeed works by recursively executing itself. And that is a known problem on Windows, because that platform is extremely slow at starting new processes for some reason. Some people have worked on alternatives (http://fastmake.org/, http://benjamin.smedbergs.us/pymake/), but afaik none of them can currently deal with everything that appears in FPC's makefiles.
