So, i've decided to go further. After making copy of that files and deleting all extensions from the names i've got errors about "not finding *.pdf, *doc" and other files in "doc directory". So i left this initiative to fix this problem this way, and i don't know what i do wrong. I've read all issues on that branch on github, but can't find any decision.

I can't speak to cygwin, but I recently (finally) got it to build and install
on mingw64 (msys2).  I had to build xmlada as static only (part of the
configure script), but I was able to make gprbuild that way.  

I will say I saw a similar issue on mingw64 when trying to build the Gnoga
library.  I don't know for sure, but I think it ended up being something
in their build environment because after a later update to one of their
3rd party libraries, the issue went away for me.  I don't know if this is
the same as what you are experiencing on cygwin though.  For me it was just
the .exe extensions (which I manually worked around by changing a gpr file
to create the filenames in a way that worked).
