What about something like:
if (value == (_svmt_s64) 0) {
  ...
}
?

If you look in constants.h (SVM_JLONG_{MIN,MAX}), the LL constants have
been removed at some point in time and replaced by constant expression
using explicit casts.

What's the difference between L and LL, is it that:
L  -> long      (32-bit on 32-bit arch)
LL -> long long (64-bit)
