Exploiting a header file shouldn't also force users to
code their own '#include <stdio.h>'. More importantly,
unless this header is mentioned in dist_noinst_HEADERS
we'd fail 'make distcheck' with the error shown below.
[ the same error will apply to all 'noinst_PROGRAMS' ]
[ that happen to use this header. but please, do not ]
[ ask me to explain exactly why or how my fix works! ]

../../proc/test_pids.c:24:10: fatal error: tests.h: No such file or directory
