Well, then those people are actually using INA90 compatibility, IMHO.

I vaguely remember that names with one leading underscore are
something special and should not normally be used/exported.  Well,
it's even possible they are in the application's domain, i. e. it
is valid for application code to define their own _LPM object.

They should use __lpm_inline() then, or maybe PRG_RDB().
