[lmi] [PATCH] Add a cast to fix compilation in 64 bits

[Vadim Zeitlin]

 Hello,

 Here is the smallest possible patch fixing the build under 64 bit Unix
systems after the changes of 75129caf03f5a5e0dd1850c6be4f06a5f231eaf9 which
resulted in an ambiguity when calling std::min<>() with the arguments of
type "long int" and "int":

Subject: [PATCH] Add a cast to fix compilation in 64 bits

Under 64 bit Unix systems the difference between two iterators, which
has std::ptrdiff_t type, is not of type "int" and hence we need an
explicit cast to make the call to std::min<>() unambiguous.

 Personally, I'd rather use InforceLives.size() and InforceLives.empty()
here too, but this is much less important than making this code compile in
the first place.

 Thanks in advance for applying this!
