--- Comment #9 from Nicola Pero <nicola at gcc dot gnu.org> 2010-12-21 11:38:56 UTC --- Sure, go ahead and create a bug for it. We can make the change for 4.6 if we make it safe. By the way, changing configure.ac is not a problem, we can do that, particularly if it makes the change safer. ;-) It could make the change safer - we could check that spinlocks are available, and use them if so; if not, we just fall back to using a standard mutex, which is slower but works on all platforms. Thanks
