OK.  This works for me too.

Some additional details:
  - the bootstrap compiler is the gnat-3.14p-nt.exe package
  - it works by configuring with a relative path, so that
    the native win32 bootstrap compiler isn't confused by 
    cygwin paths
  - the same trick doesn't work with gcc-3.2 as gnatmake chokes

The resulting cygwin 3.1 gcc works nicely as a bootstrap
compiler, so I will attempt to build ada as part of my 
regular testing.

Subject: Succsessfull GCC 3.1 with Cygwin and GNAT


Hello!

I used the lastest version of cygwin to build gcc3.1.I expirenced some
problems wich mainly where caused by myself. I renamed /gnat/bin/gcc to
/gnat/bin/gnatgcc and had gnat/bin/ in my path.

../gcc-3.1/configure --enable-threads=win32

During the configure run I checked, that a ada compiler was found and
objdir/gcc/ada was created.

After the make run with :

make CFLAGS='-O' LIBCFLAGS='-g -O2'
LIBCXXFLAGS='-g -O2 -fno-implicit-templates' bootstrap

I tried to make the ada-libs and tools with

cd gcc
make gnatlib_and_tools

This make run always ended up in an error in sysdep.c.
ICANON was not defined.

I tried to change in sysdep.c.


#if defined (linux) || defined (sun) || defined (sgi) || defined (__EMX__) \
  || (defined (__osf__) && ! defined (__alpha_vxworks)) || defined (WINNT) \
  || defined (__MACHTEN__)
#include <termios.h>

into

#if defined (linux) || defined (sun) || defined (sgi) || defined (__EMX__) \
  || (defined (__osf__) && ! defined (__alpha_vxworks)) || defined (WINNT) \
  || defined (__MACHTEN__) || defined (__CYGWIN32__)
#include <termios.h>

With this new sysdep.c I could succsessfull build and install the ada libs
and tools.

Btw.
