Portable msys/mingw upgrade

Table of Content

1) mingw

mingw-get setup tool , will install MinGW by default on C:\MinGW, msys\1.0 is under MinGW, it is the best way to install/upgrade/maintenance msys/mingw basic/core/dev pkg

Then I just copy MinGW excluding msys to \mingw as portable mingw, which including latest gcc 4.8.1-4 .

2) msys

I didn’t use msys from mingw-get since not including git, expect etc 3rd pkg, don’t want to build them from source so prefer prebuild msys collection including git, expect, perl 5.8.8 etc

then move it to \msys
