With GCC 14 I'm experiencing the following error trying to build openldap 2.6.8:

[...] In file included from ../slap.h:55, from search.c:32: search.c: In function 'ldap_back_search': ../../../include/ldap_pvt.h:531:31: error: passing argument 3 of '__gmpz_add' makes pointer from integer without a cast [-Wint-conversion] 531 | mpz_add((mpr), (mpr), (mpv)) | ^~~~~ | | | int search.c:257:9: note: in expansion of macro 'ldap_pvt_mp_add' 257 | ldap_pvt_mp_add( li->li_ops_completed[ SLAP_OP_SEARCH ], 1 ); | ^~~~~~~~~~~~~~~ In file included from ../../../include/ldap_pvt.h:519: /usr/x86_64-pc-linux-gnu/include/gmp.h:633:51: note: expected 'mpz_srcptr' {aka 'const __mpz_struct *'} but argument is of type 'int' 633 | __GMP_DECLSPEC void mpz_add (mpz_ptr, mpz_srcptr, mpz_srcptr); | ^~~~~~~~~~ make[3]: *** [Makefile:331: search.lo] Error 1 make[2]: *** [Makefile:550: .backend] Error 1 make[1]: *** [Makefile:298: all-common] Error 1 make: *** [Makefile:319: all-common] Error 1

This is with GCC 14.1.0, switching to GCC 13.2.0 instead allows the build to succeed, I checked other distributions (already on GCC 14) and git for possible patches but couldn't find anything relevant.

Complete build log is attached.
