8. Build Mingw gcc-4.6.1 - WebKit porting to Mona OS
Where are we?
- building JavaScriptCore needs ICU
- ICU needs RTTI support
- Have to build libsupc++ to support RTTI
- Have to build mingw to build libsupc++ <== We are HERE
binutils

gcc
N.B. I you build gcc serveral times for option tuning. You should "clean build", which means rm -rf gcc-4.6.1 and rm -rf ~/i586-mingw32msvc.
