[code]

The code looks OK.

> Why the linking process fails=3F=3F=3F

The short answer is: Because of the missing symbol. :-)
Indeed that's not the linker's fault, since that symbol really doesn't 
exist. What does exist is `BFont::GetFamilyAndStyle(char (*)[64], char 
(*)[64]) const'. So, the question to be answered is, what makes the 
compiler think, that the parameters are char[63]. Both the OBOS and the 
R5 header define:

#define B=5FFONT=5FFAMILY=5FLENGTH 63
typedef char font=5Ffamily[B=5FFONT=5FFAMILY=5FLENGTH + 1];
#define B=5FFONT=5FSTYLE=5FLENGTH 63
typedef char font=5Fstyle[B=5FFONT=5FSTYLE=5FLENGTH + 1];

So, using these headers things should work just fine. You haven't by 
any chance been playing with these definitions=3F

Can you point me to any or send something enabling me to reproduce the 
problem=3F I've just started a complete build, but this will take a 
while...
