This patch tries to fix the issue when PTRACE_EVENT_FORK is not found in the standard
|
|
system headers. The begininngs of this was already in place in trace.c, this patch
|
|
only takes that idea and puts it in a shared include file for trace.c *and* events.c.
|
|
The latter of which otherwise fails to build on Arm.
