Sorry, I forgot to mention that "gd1.c" should be noted before the libs:

i686-pc-mingw32-gcc gd1.c -lgd -lpng -lz -ljpeg -lfreetype -lm -DNONDLL

Here you are using the native "gdlib-config" of your system. However,
you need the one of the cross toolchain! That's what I denoted as
".../usr/" in the example command above.

Also note that Mingw-cross-env's ".../usr/i686-pc-mingw32/bin/" directory
is _not_ in the PATH and should _never_ be added to PATH.

BTW, don't confuse that with ".../usr/bin/" (outside of the "i686-pc-mingw32/"
directory), which _is_ meant to be added to PATH.


Greets,
