version 7.3.3 re-configure endlessly in AIX 4.3.3

Hi,
    While upgrade our PostgreSQL 7.3.1 to 7.3.3 on our AIX 4.3.3 box,
    I found a strange problem:
    after I
    ./configure --prefix=...
    then type:
    make
    and the build system loop endlessly with these messages:

h70:/home/postgres/postgresql-7.3.3>make
cd . && ./config.status --recheck
running /bin/sh ./configure  --prefix=/home/postgres/pgsql
--without-readline --without-zlib  --no-create --no-recursion
...


    my compiler is gcc 3.2.1 for AIX 4.3.3. any body meet the same problem.
    I guess it's the problem of our system configure(which reinstalled
recently), but still no clue what's the problem.

Thanks and regards
