[Help-smalltalk] Oh, patches!

[Eli Green]

I totally forgot that the HEAD won't compile on OS X without a few changes:

I haven't run the test suite but autoconf on OS X is 2.61 so I punted on the 
prerequisites and just changed the number. I'm surprised anybody can compile 
without multiple defined symbols right now without adding extern to the 
_gst_sem_int_vec declaration...
