Avoid dirty_init warn of incremental mode incompatible with fork on Darwin
(fix of commit 3c571c7ad)
Issue #151 (bdwgc).
To both support GC incremental mode and GC functions usage in the
forked child, pthread_atfork should be used to install handlers that
switch off GC_incremental in the child gracefully. For now, we just
disable incremental mode if fork() handling is requested by client.
Previously, GC incremental mode was disabled if parallel marker is on.
* CMakeLists.txt [APPLE && enable_handle_fork && !disable_handle_fork
&& enable_parallel_mark] (HANDLE_FORK): Do not define; update comment.
* configure.ac [$enable_handle_fork!=yes && $enable_handle_fork!=no
&& $enable_handle_fork!=manual && $THREADS==posix
&& $host==*-*-darwin* && $use_parallel_mark!=no] (HANDLE_FORK):
Likewise.
