Dimitry Andric 0c4bf57982 Fix the following -Werror warnings from clang 3.5.0, while building ... usr.bin/locate: usr.bin/locate/locate/util.c:249:29: error: taking the absolute value of unsigned type 'unsigned int' has no effect [-Werror,-Wabsolute-value] MAXPATHLEN, abs(i) < abs(htonl(i)) ? i : htonl(i)); ^ usr.bin/locate/locate/util.c:249:29: note: remove the call to 'abs' since unsigned values cannot be negative MAXPATHLEN, abs(i) < abs(htonl(i)) ? i : htonl(i)); ^~~ usr.bin/locate/locate/util.c:274:32: error: taking the absolute value of unsigned type 'unsigned int' has no effect [-Werror,-Wabsolute-value] MAXPATHLEN, abs(word) < abs(htonl(word)) ? word : ^ usr.bin/locate/locate/util.c:274:32: note: remove the call to 'abs' since unsigned values cannot be negative MAXPATHLEN, abs(word) < abs(htonl(word)) ? word : ^~~ The problem is that ntohl() always returns an unsigned quantity. In this case, it's expected to be cast back to a signed integer, but to stop complaints about abs() we just store it into an integer, and don't call ntohl() again.
