PAM_USERTYPE_UIDMIN, PAM_USERTYPE_SYSUIDMIN, PAM_USERTYPE_OVERFLOW_UID defaults not set

[mijenix]

PAM_USERTYPE_UIDMIN, PAM_USERTYPE_SYSUIDMIN, PAM_USERTYPE_OVERFLOW_UID default values are not set during configure:

...
./configure: 19197: test: x: unexpected operator
./configure: 19212: test: x: unexpected operator
./configure: 19227: test: x: unexpected operator
...

which leads to the following compilation error(s):

pam_setquota.c:178:43: error: expected expression before ',' token
  178 |           .start_uid = PAM_USERTYPE_UIDMIN,

with the following patch or specifying all the configure options --with-uidmin, --with-sysuidmin, --with-kernel-overflow-uid compilation succeeds.
