I have done a minimal installation of Cygwin-1.7 and have tried to use 
it playing to build GCC-4.4.1, but 'configure' hangs.

For example,

------------------------------------------------------------
mkdir build
cd build
CC='gcc-4' CXX='g++-4' CPP='cpp-4' ../gcc-4.4.1/configure
checking build system type... i686-pc-cygwin

checking whether we are using the GNU C++ compiler... yes
checking whether g++-4 accepts -g... yes
checking for gnatbind... gnatbind
checking for gnatmake... gnatmake
checking whether compiler driver understands Ada...
-------------------------------------------------------

Here it hangs. Task manager shows that 'gnat1.exe' take all the CPU in 
usage (50%). If I kill gnat1 with task manager, the above 'configure' 
continues:

----------------------------------------------------------------

-------------------------------------

If I use GCC3, i.e., simply running

./gcc-4.4.1/configure

it is completed without problems. Also with Cygwin-1.5, NO problems.

Cygcheck output attached.


Cheers,
    Angelo.
