This documentation error exists for all versions of gcc-3.*, gcc-4.*
documentation.

Relevant links are 
http://gcc.gnu.org/onlinedocs/gcc-4.1.1/gcc/Other-Builtins.html
http://gcc.gnu.org/onlinedocs/gcc-4.0.3/gcc/Other-Builtins.html

The error text is:
Built-in Function: type __builtin_choose_expr (const_exp, exp1, exp2)
You can use the built-in function __builtin_choose_expr to evaluate code
depending on the value of a constant expression. This built-in function returns
exp1 if const_exp, which is a constant expression that must be able to be
determined at compile time, is nonzero. 

--> Otherwise it returns 0.
should be
--> Otherwise it returns exp2.

This is confusing and misleading for the actual functionailty of the builtin,
it shold be changed.
