Hi,

on OS X 10.10.2 when building openttd 1.4.0 from source with clang and libc++ (rather than the older libstdc++), the build fails in src/fontcache.cpp because it cannot find the std::max() template for the given parameters.

The problem occurs because std::max() is called with the literal "1", which is an integer literal, and "slot->bitmap.width + BOOLEAN_EXPRESSION", which is unsigned int because the width field in FT_Bitmap is unsigned int. std::max(), however, is only defined as a template with two parameters of the same type, which "int" and "unsigned int" are not. I'm not sure whether this works with libstdc++, but this looks wrong to me.

This can be fixed by changing the integer literal to an unsigned integer literal by appending an "u". I'm attaching a patch to do this.
