# file src/foo.c forces dumping a new bootstrap-emacs, then re-byte-compiling
# all preloaded elisp files, and only then dump the actual src/emacs, which
# is not wrong, but is overkill in 99.99% of the cases.
# Note the use of single quotes in the value of vcswitness.
# This passes an unexpanded $scrdir to src's Makefile, which then
# expands it using its own value of srcdir (which points to the
# source directory of src/).
