Does anyone know what could cause these 4 seconds to become 5 min during bootstrap?
I'm not sure, but during bootstrap, the compiler hasn't been compiled yet; it's being interpreted. So it's very slow. The build process attempts to compile the compiler first, so that the rest of the build finishes faster, but the early part of the bootstrap must be done with a slow compiler.
Does bootstrap compile the file 60 times? =P
Yes, it seems so. With a slow compiler. It takes hours. It's really bad. Please try the recipe I gave Glenn: rm -f src/bootstrap-emacs src/emacs $(find . -name '*.elc') make
