Minor build issue with gendaylit using Visual Studio

My fault. For Windows, there needs to be a line:


before including math.h. Jan and Wendelin -- please make this addition to your version of gendaylit.c so the problem doesn't come back. (I had fixed this before the new check-in.)

Thanks for the heads-up, Pally!

Gendaylit fails to compile with the following error:

1>..\..\..\src\gen\gendaylit.c(186): error C2065: 'M_PI' : undeclared identifier

To use Math Constants such as M_PI in Visual Studio you need to define _USE_MATH_DEFINES -> http://msdn.microsoft.com/en-us/library/4hwaceh6.aspx
I added it to the pre-processor definitions in the project settings for gendaylit.c & it builds without error but you could add it in the source itself.
This is using the latest “combined” code from the repository at http://public.kitware.com/gitweb?p=radiance.git
