FWIW, I also happen to have the warning:
advice.c:69:2: warning: expression result unused [-Wunused-value]
error("'%s' is not possible because you have unmerged files.", me);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
./git-compat-util.h:314:55: note: expanded from:
#define error(fmt, ...) (error((fmt), ##__VA_ARGS__), -1)
^~
with clang: Ubuntu clang version 3.0-6ubuntu3 (tags/RELEASE_30/final)
(based on LLVM 3.0)
I can't say about other versions.
