Subject: [PATCH] Drop superfluous LONG_MAX/LONG_MIN fallback definitions

Both macros are supposed to be defined in limits.h (C99) and as such it
is superfluous to provide fallback definitions.  Even worse, because
these fallback definitions didn't cater to LP64, ILP64 and SILP64 data
models (and maybe some rather uncommon ones), but just assumed ILP32,
they are confusing.
