Subject: [PATCH] configure.ac: Improve C99 compatibility of IPC_RMID check
|
|
|
|
Do not call the undeclared exit function. Implicit function
|
|
declarations are likely not going to be supported by future compilers
|
|
by default, changing the outcome of this configure probe with
|
|
such compilers.
