If I adjust sqUnixUUID.c in this fashion:


#if defined(HAVE_SYS_UUID_H)
# include <sys/types.h>
# include <sys/uuid.h>
#endif

+ #if !(defined(HAVE_SYS_UUID_H)) && defined(HAVE_UUID_UUID_H)
- #if defined(HAVE_UUID_UUID_H)
# include <uuid/uuid.h>
#elif defined(HAVE_UUID_H)
# include <uuid.h>
#endif

I can happily compile the UUID plugin! I think the issue arises for me
because config finds BOTH sys/uuid.h AND uuid/uuid.h.
