My interpretation is that the problem is that the surface class have 
operators both for converting a surface object to an int as well as 
converting a int to a surface object and that code is not clear on 
what's the desired way.

I had a quick look at the code in your homedir and draw_text is defined 
in font.cpp and takes a surface object as first parameter so you 
probably want to change that line to:

return draw_text((gui != NULL ? gui->getSurface() : (surface)NULL), 
area, size, colour, txt, x, y, use_tooltips, style);
