Description Arjun Shankar 2023-03-17 14:27:27 UTC

bitcoin-core comes with a bundled version of Berkeley DB (4.8, quite old and unmaintained).  The configure script of db-4.8 encounters several "implicit int" and "implicit function declaration" errors when fragments of C in its checks are compiled as C99.  This means that future compilers that do no support implicit ints and implicit function declarations by default will fail to build bitcoin-core correctly.
