# build the dependency list for the .h files used by all sources. We do
# this in multiple passes so to avoid problems with the long command line
# generate when you slap all the sources together.
# Note that there are faster, but more environment-dependent, ways to do
# turn the output of the makemake's into an lmkfile. We avoid those
# on purpose.
