Thank you very much for the bug report.

Starting from the version 4.4 some api routines were excluded from the
package and some ones were renamed (for details please see ChangeLog).
However, for technical reasons dummy versions of these obsolete api
routines were kept for a while, and only in 4.8 they were physically
removed from the package.

In particular, lpx_set_col_coef was renamed to lpx_set_obj_coef since
its counterpart, lpx_set_row_coef, was excluded. So, you can fix the bug
simply replacing the routine name in lpglpk40.c.
