This program under development had been linking fine till I added the
references to text_appearance and text_attributes.

My assumption is -Lc:\gnat\2009\gtkada\lib in the command line pulls
the gtkada library (I suspect there is a pragma in the GtkAda source
somewhere to specify library). (I am including the gtkada.gpr).

Anycase, I should look at the syntax coloring example. I think I have
seen your Ada bindings. I will definitely take a look.
