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!
