To give a real world example, in freeradius there are
src/modules/rlm_counter/config.h.in
src/modules/rlm_eap/types/rlm_eap_peap/config.h.in
src/modules/rlm_eap/types/rlm_eap_tls/config.h.in
src/modules/rlm_eap/types/rlm_eap_ttls/config.h.in
src/modules/rlm_example/config.h.in
src/modules/rlm_ippool/config.h.in
src/modules/rlm_pam/config.h.in
src/modules/rlm_perl/config.h.in
src/modules/rlm_radutmp/config.h.in
src/modules/rlm_smb/config.h.in
src/modules/rlm_smsotp/config.h.in
src/modules/rlm_sql/drivers/rlm_sql_mysql/config.h.in
src/modules/rlm_sqlhpwippool/config.h.in
src/modules/rlm_unix/config.h.in

It would work to have each of those with
#ifndef FREERADIUS_CONFIG_H
#define FREERADIUS_CONFIG_H
....
#endif
