Today's git won't build on my system:

mesh.o mesh.c
mesh.c: In function ‘new_mesh’:
mesh.c:91: error: ‘NAN’ undeclared (first use in this function)
mesh.c:91: error: (Each undeclared identifier is reported only once
mesh.c:91: error: for each function it appears in.)
make[1]: *** [mesh.o] Error 1
make[1]: Leaving directory `/home/dimesio/wine-git/dlls/d3dx9_36/tests'
