 --with-dump-in-exec     Enable dumping into executable (enabled by default
 for `pdump', not enabled by default in combination
 with `mc-alloc').
 --with-kkcc             Enable experimental new GC algorithms.
 --with-mc-alloc         Enable experimental new allocator.
+--with-newgc            Enable new incremental garbage collector.
+--with-vdb=TYPE         Override auto-detection of virtual-dirty-bit
+write-barrier implementation for the new garbage
+collector. TYPE must be one of "auto" (for
+auto-detection), "posix", "win32", "mach", or "fake"
+(uses the new garbage collector but disables
+incremental collections). The default is to use
+auto-detection.
