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
