# Unset 'GUILE_LOAD_COMPILED_PATH' altogether while compiling.  Otherwise, if
# $GUILE_LOAD_COMPILED_PATH contains $(mcronmoduledir), we may find .go files
# in there that are newer than the local .scm files (for instance because the
# user ran 'make install' recently).  When that happens, we end up loading
# those previously-installed .go files, which may be stale, thereby breaking
# the whole thing.
