Weldon, the gc.xml needs a minor change to play with the mark-compaction GC:
<fileset dir="${src}/gc/src">
<select os="win">
- <include name="*.cpp" />
+ <include name="mark_compaction/*.cpp" />
</select>
Thanks,

I took a quick glance. Its a good start :)
I looked in both gc_v5.001.zip and GCv5-mc001.zip and did not find
gc.xmlbuild file. Also,
GCv5-mc001.zip has all its files under src directory. However,
gc_v5.001.zip does not contain any "src" directory. Thus I don't know where
to put these trees relative to each other.
Any comments, suggestions, and code contributions are welcome!
