...with Maxima 5.35.1 and wxMaxima 14.12.1. This is true even when using $. For example,

load(ezunits)$

produces

and

load(implicit_plot)$ implicit_plot (x^2 = y^3 - 3*y + 1, [x, -4, 4], [y, -4, 4]);

produces

I've just fixed the ezunits warnings (with commit [cb3981]).

Can you show us a session which leads to the second messages? I've just compiled the head of the 5.35 branch (which is basically 5.35.1). Running with SBCL, which seems to be the same as you, I get the following:

What have I missed?

In a fresh wxMaxima window:

Now, in a second fresh wxMaxima window: (%i1) load(implicit_plot); "e:/PROGRA~2/MAXIMA~1.1/share/maxima/5.35.1/share/contrib/implicit_plot.lisp"

Also, my build_info() is version="5.35.1",timestamp="2014-12-23 14:34:16",host="i686-pc-mingw32",lisp_name="SBCL",lisp_version="1.2.1"

The second problem seems to be because we copy-pasted code (sigh). See http://article.gmane.org/gmane.comp.mathematics.maxima.general/47901

Hopefully this is fixable...
