[CppAD] Too many arguments in macro defined in /usr/include

[Brad Bell]

JP:
Thanks for finding this problem. CppAD was accessing the function 
isfinite. This caused your compiler to match the function call with a 
macro defined isfinite. I have changed the call from isfinite to 
CppAD::near_equal_isfinite and hence your compiler should no longer have 
trouble with this.

If anyone has a similar error message where macros or functions in the 
system space (/usr/include in the case below) are being used improperly, 
please notify me or the CppAD mailing list.
