How can I compilie openexr with mingw - c++

Question

I am trying to compile openexr with mingw on windows7. I am gettng this error:
main.cpp: In function 'int main(int, char**)':
main.cpp:213:28: error: 'strcmp' was not declared in this scope
make[1]: *** [main.o] Error 1
make[1]: Leaving directory `/d/openexr/build/openexr-1.6.1/exrmaketiled'
make: *** [all-recursive] Error 1
Why am I getting this error and how can I slove it?
I am new in mingw and openexr, so I may did something silly!
edit1:
I am using this script to make it:
!/bin/sh
# modified synfig build file, taken from
# http://www.synfig.org/Windows_build_instructions

. ./make_openexr.conf
else

I belive the setup for mingw and mysys is not correct and the system can not find the include (and librry path). How can I check this?

As I noticed from the source code files, openexr should build with cmake tool. You have to do steps of CMake.
Otherwise compile just by g++ or gcc doesn't work.
