commit dc098405b2939146e17567a25b08fc6122893cdf
Author: pedro martelletto <pedro at ambientworks.net>
Date: Fri Sep 18 08:57:29 2020 +0200
configure.ac: add missing includes
when testing, make sure to include the relevant header files that
declare the types of the functions used by the test:
- stdio.h for printf();
- stdlib.h for exit();
- string.h for strcmp();
- unistd.h for unlink(), _exit(), fork(), getppid(), sleep().
