Compile problem

After I download postgresql-7.1.tar.gz and extract it.
Then I run ./configure , but stop at this step

checking types of arguments for accept()... configure: error: could not
determine argument types

my configure parameters are

./configure --enable-multibyte=EUC_TW --with-tcl --with-tclconfig=/usr/lib
 --with-tkconfig=/usr/lib --with-openssl=/usr/include/openssl --with-gnu-ld
 --enable-syslog

My distribution is RedHat 7.0 + CLE 1.0 ( Chinese Language Extension )
Linux kernel version 2.2.19
gmake version 3.79.1
gcc version 2.96
openssl version 0.9.5a

When I modify the parameters to :
./configure --enable-multibyte=EUC_TW

The problem still happen.

Can you tell what's the problem ?
Or what feature should I open in menuconfig of kernel compiling ?
I had choosed almost all TCP/IP features in menuconfig, and reboot .
