[Gc] libgc on Mac OS X 10.4 and Darwin X/86

My patch fixes a mach port leak that should only effect you if your  
code uses threading with a non-fixed number of threads (ie: you start  
and stop threads throughout the life of your process).  If you don't  
use threads, the main thing about libgc6.7 I would be interested in  
is the vm_deallocate() memory leak fix that's was included in 6.7.  
Both the memory leak fix in 6.7 and my mach_port_leak patch against  
6.7 would be trivial to apply to 6.5. I was able to backport both  
fixes to 6.5 in about 5 minutes when I was trying to track down the  
cause of the mach port leak I was experiencing (sorry, but I don't  
have the patched version of 6.5 lying around anymore).
