Has anyone built pgbash-7.3 against postgreSQL-8.3?

I'm curious about pgbash.  I've taken a look at the website here:
http://www.psn.co.jp/PostgreSQL/pgbash/index-e.html

According to the history on the main home page, the pgbash package was
last updated in 2003, ie:
2003.02.11 : pgbash-7.3 released (for PostgreSQL-7.3 and bash-2.05a).

I've made a start to build that package against postgresql-8.3 (on
macports).  The build failed with:

cc -O2 -I/opt/local/include/postgresql83  -c exec_sql_main.c
exec_sql_main.c:130: error: static declaration of 'sqlca' follows
non-static declaration
sqlca.h:44: error: previous declaration of 'sqlca' was here
make[1]: *** [exec_sql_main.o] Error 1
make: *** [../exec_sql/exec_sql_init.o] Error 1

It would be nice to debug this, if anyone can help?

I wonder about the general status of pgbash among the postgres
community - is it useful and is it still used?  Perhaps something else
replaced it and the development work stopped in 2003 in favor of
something else?
