I recently tried something similar to eveluate a slightly more
complex binary data structure, which ended up as a bunch of 
nested variant records with representation clauses, using almost
all possible sizes from 1..32 bits. Compiling with GNAT,
that resulted in several errors like :
'fields of "XXX" must start at storage unit boundary'
Apparently, GNAT doesn't like unaligned variant records, or is there
any way around that limitation (besides using '/'/mod/and, which
is how this stuff is handled now) ?
