cross-compiling bug

["Tim Rambo" <tmr11@..........>]

I am trying to install the library in cygwin for cross compiling. however after I configure it I get errors trying to make it.
 
I configure with:
 
./configure CC=/opt/crosstool/gcc-3.3.4-glibc-2.3.2/arm-unknown-linux-gnu-gcc CPP=/opt/crosstool/gcc-3.3.4-glibc-2.3.2/arm-unknown-linux-gnu-cpp --exec-prefx=/opt/crosstool/gcc-3.3.4-glibc-2.3.2/arm-unknown-linux-gnu/ --disable-shared --build-=i686-pc-cygwin --host=arm-unknown-linux-gnu
 
and here is the output:

I then attempt to make the library by typing:

which generates this output:

Is this a bug or am I just doing this wrong?
