I checked that the solaris breakage is from the last gc import.  I'm not
too keen about blindly importing each new release for this sort of reason.
I don't have a better suggestion though, except making gcc the official
repository for boehm-gc, as had been discussed at one time.

ISTR there was another (java?) PR related to this one.  I haven't tried a
full testsuite, but at least simple Java programs are now running for me
on sparc64.

Thanks for taking care of this.
