[ADMIN] trouble building v6.4.2 on AIX 4.3.2

[Damian Hazen]

Howdy,

I'm trying to build Postgres 6.4.2 on AIX 4.3.2 using IBM C/C++
Compilers, v3.6.4.  I'm using the aix_42 template to which I've added
the compiler flag -qlanglvl=extended.   Currently, the build is failing
with:

gmake[2]: Entering directory
`/postgres/postgresql-6.4.2/src/interfaces/libpq'
  .
  .
  .

xlc -I../../include -I../../backend   -qchars=signed -qmaxmem=8192

I've looked at the declarations for these variables and don't see what
the compiler is complaining about - ie pgsql-fe.h has 
  extern const char *const pgresStatus[];
  fe-exec.c has
  const char *const pgresStatus[] = {
        "PGRES_EMPTY_QUERY",
        "PGRES_COMMAND_OK",
        "PGRES_TUPLES_OK",
        "PGRES_COPY_OUT",
        "PGRES_COPY_IN",
        "PGRES_BAD_RESPONSE",
        "PGRES_NONFATAL_ERROR",
        "PGRES_FATAL_ERROR"
};


Thanks much for any input,
-Damian
