I got this warning while running headerscheck after this commit:

~/Desktop/projects/postgres/src/interfaces/ecpg/ecpglib/ecpglib_extern.h:221:40:
warning: function declaration isn’t a prototype [-Wstrict-prototypes]
221 | void ecpg_init_sqlca(struct sqlca_t *sqlca)

Another topic is that, CI already catched this [1] (and other not
related things in cpluspluscheck). However, it seems that since we run
headerscheck and cpluspluscheck with the '-fmax-errors=10' option; CI
didn't fail. It would be good to remove '-fmax-errors=10', though.
