Additional info:
OS = WinXP Pro SP2
The cygwin version was 1.5.8.
The original gcc release was 3.4.1.
The orginal gcc -v output was:

The exact sequence of steps involved in bootstrapping was:

bzip2 -d /gcc-4.0.1.tar.bz2
mkdir /gcc 
mkdir /gcc/4.0
cd /gcc/4.0
tar xvf /gcc-4.0.1.tar
mkdir /work
mkdir /work/install 
mkdir /work/install/etc 
mkdir /work/install/lib 
mkdir /work/install/man 
mkdir /work/install/info 
mkdir /objdir
cd /objdir
/gcc/4.0/gcc-4.0.1/configure --verbose --prefix=/work/install
--exec-prefix=/work/install --sysconfdir=/work/install/etc
--libdir=/work/install/lib --libexecdir=/work/install/lib

--with-system-zlib --disable-interpreter --enable-threads=posix
--enable-sjlj-exceptions --disable-version-specific-runtime-libs
--disable-win32-registry
make bootstrap
make install
make html

gcc unbzip2ped is 200 MB
objdir at the end is 350 MB
the process takes about 1 h

The original gcc 3.4.1 shipped with cygwin is now available on my system
with:
gcc -o hello.exe hello.c

The 4.0.1 compiler can be invoked with:
/work/install/bin/gcc

There are some errors while compiling:

1) While building "../../gcc-4.0.1/fixincludes" it says: This target
requires an assembler supporting ".machine"
you can get it from:
ftp://gcc.gnu.org/pub/gcc/infrastructure/cctools-528.5.dmg
2) While building ../../gcc-4.0.1/gcc/ggc-common.c it says storage size of
`rlim' isn't known
comment this:
  // struct rlimit rlim;
3) While compiling ../../gcc-4.0.1/gcc/toplev.c -o toplev.o it says storage
size of `rlim' isn't known and `RLIMIT_CORE' undeclared (first use in this
function)
#undef HAVE_SETRLIMIT
4) While compiling ../../gcc-4.0.1/gcc/gcc.c it says `prus' has an
incomplete type and `RUSAGE_CHILDREN' undeclared (first use in this
function)
#undef HAVE_GETRUSAGE
5) While Making all in testsuiteit says conversion from '__gnu_test::semun'
