I don't have the C experience to decide the correct way. There are currently many .c files that are including float.h conditionally or unconditionally. The condition they use is "#ifdef _MSC_VER" without a version. One idea is to include float.h from the new utils/float.h file together with math.h, and remove those includes from the .c files which would include utils/float.h. We can do this only, or together with what you suggest, or by also keeping the includes on the .c files. Which way do you think is the proper?
