New description:

 (For new arrivals not wanting to read through all the ticket comments, the
 fix is here: ProblemHotlist#clts16)

 Fresh reinstall of macports on Sequoia.
 Plenty of ports no longer compile, looks like a generic problem with Apple
 clang version 16.0.0 (clang-1600.0.26.3).

 Many of them complain about fatal error / file not found for #include
 lines with some <include> stuff, like in bug #70749

 Other ones complain (error) either during compilation or even configure
 phase about:
 «ISO C99 and later do not support implicit int [-Wimplicit-int]»
 or
 «ISO C99 and later do not support implicit function declarations
 [-Wimplicit-function-declaration]»


 Attached logs for db48, lzip, lrzsz, libssh2, python312, lz4,
 smartmontools, tmux, unrar.
