Subject: lib.c (config_set_var_n): Return a pointer even if we don't change the var.
X-Git-Url: https://git.distorted.org.uk/~mdw/runlisp/commitdiff_plain/6445760568e196c3239cdd08ec5432f96628f4cf

lib.c (config_set_var_n): Return a pointer even if we don't change the var.

Spotted by old GCC; not sure why newer versions are silent here.
