We should really join forces for the MinGW compile. The problem you have
just describes is one I have allready fixed and even got a function which
can automate the Fix:

        function Patch_MinGW ()                                                                 # {{{2

                        --unified                                                               \

                        --input=../../../SOURCES/%{Patch_File}  ;

                pushd %{Source_Dir_0};                                                          # {{{3

                                -exec /bin/bash -c Remove_NoExport '{}' ';' ;
                popd;                                                                                           # }}}3

                pushd %{Source_Dir_0}/gcc/ada;                                          # {{{3

Of corse you can just as well use a patch file. Important is to use a way to
make interim solution available for everybody. Not just the final version.
I at least do so - all my MinGW attempts are scripted or in diff files and
are committed to the subversion archive of the GNU Ada project [1].

Anybody is welcome! Those who don't like my Cygwin/RPM approach can use my
RPM-Spec to Bash-Script converter and continue from there. But we should
not need develop patches twice!

Also: I got diff patches which remove the warnings GNAT/GPL or GNAT/Pro
issue when compiling GNAT/GCC. That might be an option as well.

So get yourself a sourceforce user and issue a support request to become a
member of the GNU Ada Project!

You missed nothing - there is none. The way you join a project depends 
on how many admins are there. If there is just one send him or her an 
E-Mail. If there are more administrator then then it is generally better 
to raise an support request which will be attended to by the first admin 
to take notice.

The GNU Ada project has 4 admins and the link to follow is:
