Hello,

This may not give all the answers you could expect, however, here are so=
me  =

hints : GNAT+GPS on Windows is already based on MinGW, so with a GNAT+GP=
S  =

installed and a MinGW installed, you have two different MinGW installed.=


I have both two, and mostly use the =E2=80=9Cpure=E2=80=9D MinGW and les=
s oftenly  =

GNAT+GPS. To avoid troubles, as both are in the PATH, when I know I will=
  =

use one and not the other, I rename the directory containing the one I  =

will not used (ex. =E2=80=9CGNAT=E2=80=9D -> =E2=80=9CGNAT disabled=E2=80=
=9D, or =E2=80=9CMinGW=E2=80=9D -> =E2=80=9CMinGW  =

disabled=E2=80=9D). This solve some troubles.

Then, MinGW is based on GCC, and GCC on Window may *or may not* use the =
 =

Windows registry for its configuration, depending on one dedicated build=
  =

option. As much as you can, or if you are not afraid to build your own i=
f  =

needed, try to use a MinGW with a GCC which does not make use of the  =

registry, in order to avoid conflicts.

I use MSys too, and the tip of renaming the directory containing the  =

compiler which is not to be used, works nice here. I can't ensure this  =

will work for you too, however, can you try and tell about the result ?

There is even better than a pragma Assert: a SPARK --# check.
