Yeah!

Hm - being utterly ignorant about Cygwin dll internals, I can at
least report that it seems to be possible to compile (and link
them to the corresponding libstdc++.a and libgcc.a libraries) the
Cygwin dll itself without the standard option -fno-rtti -fno-exceptions.
 

By re-adding the --fno-exceptions  option to the compilation of
winsup/cygwin/lib/_cygwin_crt0_common.cc one seems to also get
a  fully functional  libcygwin.a library - i.e. running the 
test suite resulted in nine failures and no pthread failure. 

(Without re-adding the option -fno-exceptions to the compilation
of _cygwin_crtO_common.cc one gets a link error ala
.. libcygwin.a(_cygwin_crt0_common.o):
In function `_cygwin_crt0_common':
.. /src/winsup/cygwin/lib/_cygwin_crt0_common.cc:41: 
undefined reference to `___gxx_personality_v0'.)

Cool ... using basically the same options and sources I was able to 
compile the Ada extension + libs + tools (the compilation of gnatdll
required a minor tweak).

I take that that it is still not possible to compile libgjc?

For my native bootstrap I had to explicitly copy cygming.h into
the build directory  Objdir/gcc/gcc to make things work.
