Problems building GNU Prolog 1.2.19 on Debian GNU/Linux 3.1 (r1)

[Roberto Bagnara]

Compilation aborts as follows:

gplc -c -C '-O3 -fomit-frame-pointer' engine.c
engine.c: In function 'Call_Prolog':
engine.c:318: error: invalid lvalue in assignment
engine.c:331: error: invalid lvalue in assignment
engine.c: In function 'Call_Prolog_Next_Sol':
engine.c:351: error: invalid lvalue in assignment
engine.c:359: error: invalid lvalue in assignment
engine.c: In function 'Keep_Rest_For_Prolog':
engine.c:380: error: invalid lvalue in assignment
engine.c:386: error: invalid lvalue in assignment

A full log of configure + make is below the signature.
Does anyone know how to fix it?
Many thanks in advance,

    Roberto
