windows xp compile error

I'm new to working with this stuff so please excuse any obvious issue I may
have overlooked.
I downloaded the 8.0.3 release source code.
I'm trying to compile on windows xp pro here is my make install output
after having ran ./configure without zlib option without any error.

sh-2.04$
Any ideas why I'm getting this? Here is what version I get when running
make --version
