archivers/pax build failure on Linux

[Benny Siegert <bsiegert%gmail.com@localhost>]

Hi!

I have an exciting new bit of build breakage in archivers/pax. This is 
on Fedora Asahi Linux with GCC 14.1.1.

cc -DHAVE_CONFIG_H -DHAVE_NBCOMPAT_H=1 
-I/home/bsiegert/pkgsrc/archivers/pax/work/libnbcompat -I. -I. -O2 -c 
getid.c
getid.c: In function 'setup_getid':
getid.c:156:13: error: implicit declaration of function 
'pwcache_groupdb' [-Wimplicit-function-declaration]
  156 |         if (pwcache_groupdb(gi_setgroupent, gi_endgrent,
      |             ^~~~~~~~~~~~~~~
getid.c:158:16: error: implicit declaration of function 'pwcache_userdb' 
[-Wimplicit-function-declaration]
  158 |             || pwcache_userdb(gi_setpassent, gi_endpwent,
      |                ^~~~~~~~~~~~~~
*** [getid.o] Error code 1

The thing is, I don't understand how this is supposed to work. 
libnbcompat provides implementations for the pwcache functions but no 
header declaring them, as far as I can see. And pax uses the pwcache 
functions unconditionally.

Can someone explain this to me?
