[Mingw-cross-env-list] git branch makes MXE recompile everything

[William]

Hello,
I noticed this very bad thing : if you are on the mxe directory, and 
change the branch :
$ git checkout my_branch
then go back to master :
$ git checkout master
Then MXE is tricked and if you want to compile something, it recompile 
everything !
This does not happen all the time, I think that it only happens when the 
branch actually changes some files, don't known which ones.

Does anybody have an idea how to solve this ?

Personnaly, I am not a big fan of branches, but Volker asks us to use 
them before sending pull requests ;-)


Regards,
William
