When openldap package is being built in Gentoo GCC C compiler highlights a few problems of implicit function declaration usage as [1]. I've hacked up patches against current master: [2]
Why those are problems? implicit function declarations mean the function type will be defaulted to int(int, int).
For functions like int slap_sasl_cbinding( Connection *conn, struct berval *cbv ); it might cause pointer-to-int truncation on 64-bit platforms.
Simplest way to reproduce the failure is to switch warning into failure as: ./configure CFLAGS="-Werror=implicit-function-declaration" make
Many projects enable -Werror=implicit-function-declaration by default to catch that type of failure at development time.
Thank you!
