Have you ever planed to have a "POSIX" root folder? i.e. a folder like c:\POSIX which contains "bin" "usr" "etc" ... And why don't you ship mingw/msys in that folder with all standard reactos distributions ?
Because: 1) It is the first step for developing reactos in reactos ... 2) All unix-like applications can be installed there and will not have to create each time their own POSIX tree. 3) It is to be ready to a massive port of gnu softwares that don't need a full POSIX compliant OS. 4) It is mandatory for a future POSIX subsystem. 5) It is cool and sexy.
