"databases/db5" build fails on -current/sparc?

["John D. Baker" <jdbaker%consolidated.net@localhost>]

This was observed on pkgsrc-HEAD during the freeze for pkgsrc-2026Q2
with -current sources updated to the same time-frame, so I believe the
observation to still be relevant (for all those who'll fuss about only
using pkgsrc-HEAD w/-current).

Attempting to build "databases/db5" on -current sparc (11.99.6 as of 17
June 2026) fails during the configure phase with:

[...]
checking for socklen_t... yes
checking for ANSI C exit success/failure values... yes
checking for getopt optreset variable... yes
checking for mutexes... UNIX/fcntl
configure: error: Support for FCNTL mutexes was removed in BDB 4.8.
*** Error code 1

Stop.
make[1]: stopped making "all" in /x/pkgsrc/databases/db5

Similar failures appear for further "conftest.c" variants following the
one above.

Since "databases/db5" built without complaint on netbsd-11/sparc
(11.0_RC5), the problem here is likely related to GCC 14+'s stricter
behavior.  I've not yet tried building "databases/db5" on any other arch
with -current.
