Clang 8 warns that adding a string to an integer does not append to string. Indeed it doesn't, but that was not the intentetion. Use array indexing as suggested by the compiler to silence the warning. There should be no functional change.

Example of warning message:

alpm.c:71:54: warning: adding 'int' to a string does not append to the string [-Wstring-plus-int] sprintf(hookdir, "%s%s", myhandle->root, SYSHOOKDIR + 1); ~~~~~~~~~~~^~~ alpm.c:71:54: note: use array indexing to silence this warning sprintf(hookdir, "%s%s", myhandle->root, SYSHOOKDIR + 1); ^ & [ ] 1 warning generated.

Ack. My solution was to switch back to gcc!
