I'm going over the url you gave.  I got up super early today for my 
daughter who is going to study comp-sci this fall(!); so I  really 
do need more coffee or a *nap*.  meanwhile, below is a testfile that
print N labels [[ here N == 3 ]]. Id send you the makefiles, but figure 
you can mouse the gcc line.  "x2" is my lack of imagination.  

at any rate, iv'e used the GTK__MISC string--macro? everything I'm coding 
from now on is 3.0, so could you edit in the recommended way?  you've got 
halign; shouldn t I use the valign for mmy labels?  

tx much,
	gary
