Ok, so the right fix is to email anybody who posted code using struct
bpf_program to fix their code ? :-)

My question was more along the lines of should we attempt changing one
of the two variants to make them match on BE (since they are in effect
compatible on LE), tho of course this could have the usual annoying
consequence of breaking the mangled c++ name of the symbol).

up users and fix them. Great....

Cheers,
Ben.
