Avoid implicit function declarations. The change around ac_declaration
|
||
|
|
always includes <stdlib.h> for the exit prototype. For
|
||
|
|
ac_cv_header_stdc, use return from main instead of exit.
|
||
|
|
|
||
|
|
configure.in is not updated because these faulty checks are generated
|
||
|
|
by an old version of autoconf.
