bug in compiling, with win32

[NemboKid will never die (PriviJunior)]

Hello gentle Gnu staff.
I'm a student of computer science at university of Milan.

We have to learn Prolog, so I've installed your Gnu Prolog, version 1.2.16 (with the auto installing setup file), and my computer is a Pentium II with Windows 98.
I've read nearly all the whole documentation of your wonderful program, but what a frustration I had when I wanted simply compile a prolog file!
The trace of the prompt Dos is auto-explainant:


D:\Documenti>gplc -v hook.pl

delete C:\WINDOWS\TEMP\gplc4.asm

Practically lacks an exe-file, that should be "nasm.exe" under the "prolog\bin" directory,
that should compile an Assembly file into an Object file.

I hope there's an easy way to solve this problem.
I thank you a lot for a possible reply!
