This is because NASM treats conditional jumps as short by default.
If you need longer jumps then use something like

    jz NEAR mylabel

This is explained in section 10.1.2 of the NASM manual.

I don't know what this has got to do with DJGPP.  If you have further
questions about NASM you would be better asking in alt.lang.asm or
comp.lang.asm.x86.
