I can, but in order not to reinvent the wheel I'll use RMS's code
(section "Naming an expression's type" from /Using and Porting GNU CC/)

     #define max(a,b) \
       ({typedef _ta = (a), _tb = (b);  \
         _ta _a = (a); _tb _b = (b);     \
         _a > _b ? _a : _b; })

Gotta love those GCC extensions.  (Okay, so it won't work in ANSI C. 
Can you write a single function or macro in it, or ANSI C++, that will
safely find the maximum of two arguments of any types?)
