> In the case of Mingw64 the base path is taken from options (it seems),
while in the case of mingw32 it is hard-coded to the C:/ directory. Do you
think it would be possible to supply this parameter at runtime too ? It
would avoid the necessity to edit this file when one has not installed
mingw on C:/
(Note: the option could perfectly default to C:/mingw)
