elog.c comiple problem on AIX 4.2.1

I am still getting the duplicate case value problem trying to compile the
CVS head on AIX 4.2.1.

gmake[4]: Entering directory
`/usr/local/postgres/pgsql/src/backend/utils/error'
gcc -O2 -pipe -Wall -Wmissing-prototypes -Wmissing-declarations
-I../../../../sr
c/include -I/usr/local/ssl/include -c -o elog.o elog.c
elog.c: In function `errcode_for_file_access':
elog.c:546: duplicate case value
elog.c:539: previously used here
gmake[4]: *** [elog.o] Error 1
gmake[4]: Leaving directory
`/usr/local/postgres/pgsql/src/backend/utils/error'
gmake[3]: *** [error-recursive] Error 2
gmake[3]: Leaving directory `/usr/local/postgres/pgsql/src/backend/utils'
gmake[2]: *** [utils-recursive] Error 2
gmake[2]: Leaving directory `/usr/local/postgres/pgsql/src/backend'
gmake[1]: *** [all] Error 2
gmake[1]: Leaving directory `/usr/local/postgres/pgsql/src'
gmake: *** [all] Error 2

Is this problem going to be fixed for version 7.4 or is there a work
around available?
