[ODE] more problems while building :-)

[Nicolas Weber]

Hi again,

I had to add
#define alloca(size) __builtin_alloca(size)
to
drawstuff.cpp
to compile with mingw. I get problems during linking with make ode-test 
and drawstuff-test however (lots of 
"lib/libdrawstuff.a(drawstuff.o)(.text+0x5d5):drawstuff.cpp: undefined 
reference
to `operator delete[](void*)'"). Can you help me? (and test_ode.exe 
gives "ODE internal error 0" "A*x = b+w, maximum difference = 
3.433228e-005" while dTestSolveLCP(), but I compiled with single precision).

TIA,
Nico
