patch for confbase.Y/config.Y

Yo! Ran into an issue where I couldn't use a function with 32 bit AS numbers. Made the following changes and got it working: bash-4.1# diff conf/confbase.Y ../bird-1.3.2/conf/confbase.Y 30c30 < check_u32(unsigned val) ---

check_u16(unsigned val) 32,33c32,33 < if (val > 0xFFFFFFFF) < cf_error("Value %d out of range (0-4294967295)", val);

if (val > 0xFFFF) cf_error("Value %d out of range (0-65535)", val);

bash-4.1# diff filter/config.Y ../bird-1.3.2/filter/config.Y 307c307 < term { $$ = f_eval_int($1); check_u32($$); } ---

term { $$ = f_eval_int($1); check_u16($$); } 420c420 < check_u32($2->a2.i); check_u32($4->a2.i);

check_u16($2->a2.i); check_u16($4->a2.i);

Feel free to use it :) //Rasmus
