to do when regenerating:

in .hh file:

add __SUNPRO_CC ifdefs for single_value_struct

delete encode/decode members except for EXTERNAL

in .cc file:

leave transfer syntax in anonymous namespace

delete encode/decode members except for EXTERNAL
leave EXTERNAL::BER_encode_TLV() -- written by hand
leave EXTERNAL::BER_decode_TLV() -- written by hand

replace '@EXTERNAL' with 'EXTERNAL'

remove RAW and TEXT enc/dec functions
