 Hi Alan,

 Ada bindings and example work now for the MinGW environment. Apart from
 the fix below I only needed a small change - instead of TARGET.adb I
 used TARGET_BASE.adb, since TARGET_BASE is the target name without
 suffix. I also checked that changes in Linux, so these changes should
 have no impact on Linux and Mac OSX.

Thanks, Werner.  That's a nice solution.  Out of curiosity where did you
find TARGET_BASE documented?

Also, thanks for implementing example 12 in Ada and discovering that the
thin interface does not (yet) terminate the C strings with a null (which
should help Jerry find a good solutions for this issue).

BTW, this morning I was in off-list contact with Jerry about sorting out a
CMAKE_LIBRARY_PATH issue for libgnat.  I believe that should be the last
CMake issue for him.  This means as of today he should finally be in good
position to start dealing with the backlog of Ada interface issues that has
been discovered.

 Hi Alan,

 I just found an easy fix for the object file ending problem. In
 CMakeAdaCompiler.cmake.in change the last lines to:

 IF(UNIX OR MINGW)
   SET(CMAKE_Ada_OUTPUT_EXTENSION .o)
 ELSE(UNIX OR MINGW)
   SET(CMAKE_Ada_OUTPUT_EXTENSION .obj)
 ENDIF(UNIX OR MINGW)

 If you think this workaround is ok, I will submit these changes.

Good catch, Werner. Please go ahead immediately with that commit.

That leaves just the executable suffix issue.  I think the thing to do there
is to play with SET_TARGET_PROPERTIES (in ada/examples/CMakeLists.txt) until
you get something that works.  For example, it appears you have control of
the output name and/or the SUFFIX. If you can get a build of x01 that way,
then to actually get it to execute on MinGW and Cygwin I understand (from
informed opinion on the CMake list, :-) ) that you will have to copy x01 to 
x01.exe.  I think the easiest way to do that is with a cmake -e copy command
in ada/examples/CMakeLists.txt using the add_custom_command signature that
modifies a target result.

Anyhow, please play with this executable suffix issue and commit it if you
can get something to work on MinGW.  I will clean up afterward if necessary.
