Hi,
I tried editing V8 to see what I could get working for MINIX.
Thankfully, unless I changed something I shouldn't have, "src/
jsregexp.cc" is no longer an issue for me on MINIX. :)
Sadly, V8 still doesn't work on MINIX 3, and now I have problems with
"src/platform-nullos.cc."
Here are my changes to V8 (svn diff > changes.diff):
