+Subject: [PATCH] pam_pwquality: add include for
+ pam_modutil_check_user_in_passwd
+
+After 9084c1b032161cdb53d5f66132a91bdc207faecf, one gets:
+```
+pam_pwquality.c: In function 'check_local_user':

+cc1: some warnings being treated as errors
+make[2]: *** [Makefile:634: pam_pwquality.lo] Error 1
+make[2]: *** Waiting for unfinished jobs....
+```
+
+We need to include security/pam_modutil.h when appropriate.
