I get the same warning when compiling the new 2.3.x stuff.

I looked into it, and found the following in the documentation in 
pango-1.3.0 about pango_context_new:


This function is only useful when implementing a new backend for Pango, 
something applications won't do. You should use the context creation 
function for the backend you are using, for example, 
pango_xft_get_context() <cid:part1.02010100.02050406@broadpark.no>, 
pango_win32_get_context() <cid:part2.09020808.07090900@broadpark.no> or, 
pango_ft2_font_map_create_context() 
<cid:part3.09030405.01070606@broadpark.no>.

If you are using Pango as part of a higher-level system, that system may 
have it's own ways of create a PangoContext 
<cid:part4.07000700.03030809@broadpark.no>. For instance, the GTK+ 
toolkit has, among others, gdk_pango_context_get_for_screen() 
<file:///home/lfs/gtk-2.3.0/pango-1.3.0/docs/gdk/gdk-Pango-Interaction.html#gdk-pango-context-get-for-screen>, 
and gtk_widget_get_pango_context() 
<file:///home/lfs/gtk-2.3.0/pango-1.3.0/docs/gtk/GtkWidget.html#gtk-widget-get-pango-context>.
