[ODE] Building on MacOSX (and now Linux)

[Rodrigo Hernandez]

I am getting the same isnanf error on MinGW, the funny thing is that 
configure does find the function,
aparently, this has to do with gcc vs g++ (configure uses gcc for it's 
tests), it seems rather odd that gcc has
a function and g++ doesn't, but it seems to be so, this feels more like 
a GCC bug than anything else.
