This is no problem for user-space programs since defines (U)INT32_MAX along with (u)int32_t. For the kernel space, libfdt_env.h needs to be adjusted before we pull in the changes. In the kernel, we usually use s/u32 instead of (u)int32_t for the fixed-width types. Accordingly, we already have S/U32_MAX for their max values. So, we should not add (U)INT32_MAX to any more. Instead, add them to the in-kernel libfdt_env.h to compile the latest libfdt.
