Compile problem on gcc-4.2-20060204

Hi, 

I came across the following problem while I was trying to compile
gcc-4.2-20060204 on RedHat Linux. 

checking for shared library run path origin... (cached) done
checking for iconv... (cached) yes
checking for iconv declaration... (cached)
         extern size_t iconv (iconv_t cd, char * *inbuf, size_t
*inbytesleft, char * *outbuf, size_t *outbytesleft);
checking for X... disabled
configure: error: GTK+ peers requested but no X library available
configure: error: /bin/sh
'/root/GCC/gcc-4.2-20060204/libjava/classpath/configure' failed for
classpath
make[1]: *** [configure-target-libjava] Error 1
make[1]: Leaving directory `/root/GCC/gcc-build'
make: *** [bootstrap] Error 2

The shell script I use to call ./configure is:

GCC_SRC_DIR=/root/GCC/gcc-4.2-20060204

export BOOT_CFLAGS='-g0 -O2 -pipe'
export CFLAGS='-g0 -O2 -pipe'
export CXXFLAGS='-g0 -O2 -pipe'
export DEBUG_FLAGS='-g0'
export LDFLAGS='-s'

export LIBRARY_PATH=/usr/lib:/usr/X11R6/lib

$GCC_SRC_DIR/configure --enable-languages=c,c++,java --enable-threads\
    --disable-nls --disable-debug \
    --with-gcc --with-gnu-as --with-gnu-ld \
    --disable-shared \
    --enable-libgcj --enable-java-awt=gtk,xlib --without-x
--enable-java-gc=boehm \
    --disable-libgcj-debug

The shell script I use to make is:
MAKE=make

$MAKE \
    BOOT_CFLAGS='-O2 -pipe -g0' \
    CFLAGS='-O2 -pipe -g0' CXXFLAGS='-O2 -pipe -g0' \
    LIBCFLAGS='-O2 -pipe -g0' \
    LIBCXXFLAGS='-O2 -pipe -g0 -fno-implicit-templates' \
    DEBUG_FLAGS='-g0' LIBGCC2_DEBUG_CFLAGS='-g0' \
    JCFLAGS='-pipe -g0' GCJFLAGS='-O2 -pipe -g0' \
    LIBGCJ_CFLAGS='-O2 -pipe -g0' \
    LIBGCJ_CXXFLAGS='-O2 -pipe -g0 -fno-implicit-templates' \
    LDFLAGS='-s' bootstrap

I am not sure I have set the parameters right. Any suggestions are
highly welcomed. 

Regards
Rui
