I also got the following error when compiling DOLFIN in Windows:

g++-sjlj -o dolfin\mesh\ALE.o -c -Wall -pipe -ansi -DDEBUG -g -Werror
-DNDEBUG -O2 -DPACKAGE_VERSION=\"0.7.3\" -I. -IC:\local\include
-IC:\boost_1_35_0 -IC:\local\include\libxml dolfin\mesh\ALE.cpp
dolfin\mesh\ALE.cpp: In static member function 'static void
dolfin::ALE::hermiteFunction(dolfin::real**, dolfin::uint, dolfin::Mesh&,
dolfin::Mesh&, const dolfin::MeshFunction<unsigned int>&, const
dolfin::MeshFunction<unsigned int>&)':
dolfin\mesh\ALE.cpp:247: error: 'M_PI' was not declared in this scope
scons: *** [dolfin\mesh\ALE.o] Error 1
scons: building terminated because of errors.

Including math.h in ALE.cpp doesn't help, so I simply defined M_PI
explicitly:

#ifndef M_PI
#define M_PI 3.14159265358979323846
#endif

There are probably better ways, but it's a quick fix (patch is attached).
