Bugs in gprolog.h (GNU Prolog 1.3.0)

User-agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20050929 Thunderbird/1.0.7 Fedora/1.0.7-1.1.fc4 Mnenhy/0.7.3.0 

The bug in the header file gprolog.h already reported in 2002
(http://lists.gnu.org/archive/html/users-prolog/2002-09/msg00000.html)
is still there.  That is, the version installed by GNU Prolog
1.3.0 contains the following variable declarations
at lines 1947, 1948 and 2096, respectively:

int last_read_line;
int last_read_col;
...
unsigned *byte_code;

Header files should never contain such things in order to
avoid the obvious link-time errors.
All the best,

    Roberto
