I've included your code in pgsql2shp.
It would be needed for postgis_inout.c
and postgis_gist*.c where its computation
time will be more noticeable.
I've asked to the pgsql-hackers about using their computed
BYTE_ORDER. Yet, I'd see better having Dave's code as an m4 macro
and postgis switch to autoconf.
