I'm not sure what the "empty declaration" warnings are, but
they look harmless. The "line 61: zero-sized struct/union"
is referring to there being an empty struct in
tomcrypt_prng.h:61, since all the elements are #defined out.
I _think_ the syntax is legal (though not 100% sure), but you
can work around it by adding "int dummy;" or something like
that just below the "typedef union Prng_state" line.

It should be fixed in 0.49.

Cheers,
Matt
