[ODE] Building on MacOSX (and now Linux)

Hi all,

Just sent Rodrigo a fixed version of osx.cpp that compiles also using  
gcc-3.3 (at least on my system: OS X 10.4.6 Tiger).
All of ode now compiles just fine with both gcc 3.3 and 4.0.1 after  
renaming test_chain1.c to .cpp and adding LINK=$(CXXLINK) to  
Makefile.am in ode/src.

Googling for isnanf, I found the following:
http://lists.apple.com/archives/Unix-porting/2004/Aug/msg00066.html

Could someone who is having the problem just try to change the call  
from isnanf to isnan and see if that fixes the problem?

- Samuli
