it's just an eccentricity of autoconf. It stores a symbol that's the
concatenation of the symbol it's looking for, and the place it finds it.
The first uid_t test is a side-effect of the (canned) getgroups test.
The second is explicit (and if I'd noticed it -- and knew that the
getgroups test _always_ tests for uid_t -- could remove it).
