I know this, I meant the precautions and gotcha's MSYS sometimes has, like
the link.exe issue we are having here.
My PATH from within MSYS is this:
.:/usr/local/bin:/mingw/bin:/bin:/c/Program Files (x86)/MiKTeX
2.8/miktex/bin:/c/Windows/system32:/c/Windows:/c/Windows/System32/Wbem:/c/Windows/System32/WindowsPowerShell/v1.0:/c/Program
Files/MATLAB/R2010a/runtime/win64:/c/Program
Files/MATLAB/R2010a/bin:/c/Program Files (x86)/MKVtoolnix
I'm guessing /usr/local/bin is /bin, and mingw/bin is set by the postinstall
script to wherever you have a mingw compiler installed

I'll get that in the wiki. Thanks for the explanation.
