## Generate `dmakeroot.h' in two cases
## 1. `config.status' is run either explicitly, or via configure.
##     Esp. not when it is run in `Makefile' to generate makefiles and
##     config.h
## 2. CONFIG_OTHER is set explicitly
##
## Case 1 is difficult.  We know that `automake' sets one of
## CONFIG_FILES or CONFIG_HEADERS to empty.  This heuristic works
## only when AM_CONFIG_HEADER is set, however.

if test -n "${CONFIG_FILES}" && test -n "${CONFIG_HEADERS}"; then
	# Both CONFIG_FILES and CONFIG_HEADERS are non-empty ==> Case 1
