Problems linking to calloc

[Brett Swimley]

I suppose I should report that I've been working a bit with Mark (but on 
a separate application) and have Microwindows up and running with Nano-X 
and freetype2 on a small (PDA sized) LCD display.  I've used quite a bit 
of Rosimildo's work.

I'll get some info together.

Regards,

Brett Swimley
