Over all it looks not to bad.

For the acats tests most of the FAIL cases ar of the form:
violation of restriction "NO_IMPLICIT_DYNAMIC_CODE" at system.ads:44

The same is true for the gnat tests.


gcc tests show several ICEs:
gcc.c-torture/compile/20001226-1.c with optimization different than -O0
gcc.c-torture/compile/limits-declparen.c with optimization -O3
gcc.c-torture/compile/limits-exprparen.c
gcc.c-torture/compile/limits-pointer.c -O3 -g -w
gcc.dg/20020425-1.c -ansi -pedantic-errors -S
gcc.dg/pch/largefile.c

Hope that helps to improve further.

Cheers,

Rainer

This very likely means that the compiler is misconfigured.  Try to replace
"cygwin32" with "cygwin" in ada/gcc-interface/Makefile.in and rebuild the 
runtime (make all-target-libada).

  I have these patches against 4.3.2/4.3.3 that should help with this.  (Sorry
Eric, I've been too busy with the cygwin gcc distro releases to start feeding
these upstream yet, but they need to wait for 4.5 anyway.  They're not all in
entirely suitable shape yet either.)

    cheers,
      DaveK

Thanks for stepping in.  I thought GNAT could at least be built on cygwin, but 
apparently it cannot anymore.  I think that we should try to make it build 
again for 4.4 by merging just enough of your changes.

  Of the stuff in the previous email, I would reckon that the necessary parts
are probably:

-ifeq ($(strip $(filter-out cygwin32% mingw32% pe,$(osys))),)
+ifeq ($(strip $(filter-out cygwin% mingw% pe,$(osys))),)

.. that change to ensure the windows-specific target-pair overrides, and the
gsocket.h patch.  The sysdep.c changes might also turn out to be required to
prevent the build failing at a slightly later stage.

  Most of the other changes are not suitable for 4.4.  (The
ADA_CFLAGS->ALL_ADA_CFLAGS and T_ADA_CFLAGS changes are probably entirely
superfluous, they were parts of earlier attempts to resolve EH issues which I
believe were in fact fixed in their entirety when I figured out to change
ZCX_By_Default, but I haven't had time to re-test with them removed yet.)

    cheers,
