stefanct suggested that in #[e-mail].

I was mainly led on the wrong path, but the warning saying the result is u32, and wanted to use the corresponding length modifier.

From fizzie in ##c:

,cc uint32_t u = 0; size_t s = 0; __typeof__(u - s) combined; ptype(u); ptype(s); ptype(combined);
    → u = unsigned int   s = unsigned long   combined = unsigned long

,cc -m32 uint32_t u = 0; size_t s = 0; __typeof__(u - s) combined; ptype(u); ptype(s); ptype(combined);
    → u = unsigned int   s = unsigned int   combined = unsigned int
