[ODE] Building on MacOSX (and now Linux)

[Samuli Riihonen]

I have no problems with isnanf.
test_basket compiles (and runs) fine, so it's not a general problem  
with gcc or PPC.

As to the linking problem on osx, test_chain1.c will compile if it is  
renamed to cpp.
Linking libode.dylib will also work if the LINK -command in the  
Makefile is changed to CXXLINK.

I tried to understand the automake system to find out where it  
decides which linking-method to use for the said dylib, but failed  
miserably :)
