Well, probably not that interesting.  Though I found some things.
=46irst the warnings:

parse.c:846: warning: `is_ud_function' defined but not used
plot3d.c:1159: warning: `specs' might be used uninitialized in this function
=2E./term/wxt.trm:112: warning: `font_setting' might be used uninitialized =

this function
wxterminal/gp_cairo.c:1029: warning: `overprinted_width' might be used=20
uninitialized in this function

The first one is recently introduced, the second one seems to be
false alarm.  Of the third one I've heard similar diagnose on the
list.

Is this a problem with the installation of the libs?
