Subject: [PATCH] configure: C99 compatibility issues
|
|
|
|
As part of this effort:
|
|
|
|
https://fedoraproject.org/wiki/Toolchain/PortingToModernC
|
|
|
|
I've found an issue with one of the autoconf checks in the conntrack
|
|
package. It uses the exit functions without including stdlib. This is
|
|
deprecated in C99 because it no longer allows implicit function
|
|
declarations. Find attached a patch that changes the check to use return
|
|
instead of exit.
