The src directories in opensmalltalk-vm github are just caches - meant 
to avoid transpilation overheads during repeated builds. The original 
Smalltalk/Slang source is at http://source.squeak.org/VMMaker.html 
repository in two packages:

* VMMaker.oscog package - OpenSmalltalk VM - active development, 
platforms+build code is at github.com/OpenSmalltalk/opensmalltalk-vm. 
Proposed patches go into VMMakerInbox repo on the same server.

* VMMaker package - Squeak Interpreter VM (compatible with 6502 format 
images), maintenance mode. platforms+build code in SVN repo 
(squeakvm.org/svn/squeak/trunk/platforms). src cache is also on the same 
SVN.

So "forking" github would only fork platforms/ part of VMMaker.oscog and 
not to its src/ parts.
