Yeah, annoying.  But I'm not sure it's even possible for
the compiler to discover that one.
But something good did come of it: when I was looking at it
yesterday.  I noticed bugs in that use of strtol.

E.g., the caller silently truncates a 64-bit long value to
the "int" return value.   Also, it doesn't detect overflow.

Will send a patch later today, unless someone else wants to do it.
