Literal quote character causes exception.

[Nicolas Pelletier]

Hello,

I found the following behaviour both in GNU Prolog 1.3.1 and GNU
Prolog 20090310, which I believe is incorrect:

address@hidden:~/tmp$ gprolog
GNU Prolog 1.3.2

| ?- X = 0''.
uncaught exception: error(syntax_error('user_input:1 (char:8) quote
character expected here'),read_term/3)

I expected the substitution X = 39 as the result of my query. Would
you please look into this problem ?

Thanks in advance.
