xauth warning: WRITES macro

[Thomas Klausner]

Hi!

clang doesn't like the WRITES macro xauth uses:

process.c:867:3: warning: if statement has empty body [-Wempty-body]
                WRITES(STDERR_FILENO, "\n");
                ^
process.c:641:57: note: expanded from macro 'WRITES'
#define WRITES(fd, S) {if(write((fd), (S), strlen((S))));}
                                                        ^
process.c:867:3: note: put the semicolon on a separate line to silence this warning
process.c:641:57: note: expanded from macro 'WRITES'
#define WRITES(fd, S) {if(write((fd), (S), strlen((S))));}

Why is there an empty if, anyway?
