If __lxstat() and __xstat() functions are not available, build fails with: CC virfilewrapper.o virfilewrapper.c:180:5: error: no previous prototype for function '__lxstat' [-Werror,-Wmissing-prototypes] int __lxstat(int ver, const char *path, struct stat *sb) ^ virfilewrapper.c:208:5: error: no previous prototype for function '__xstat' [-Werror,-Wmissing-prototypes] int __xstat(int ver, const char *path, struct stat *sb) Luckily, we already check presence of these functions in configure using AC_CHECK_FUNCS, so just don't wrap these if they're not available.
