Compile ucspi-tcp-0.88 on Red Hat Enterprise Linux Client release 5.5 (Tikanga)

Compiling ucspi-tcp version 0.88 on Red Hat ES 5.5 fails with the following error:

./load tcpserver rules.o remoteinfo.o timeoutconn.o cdb.a \
        dns.a time.a unix.a byte.a  `cat socket.lib`
/usr/bin/ld: errno: TLS definition in /lib/ section .tbss mismatches non-TLS reference in tcpserver.o
/lib/ could not read symbols: Bad value
collect2: ld returned 1 exit status
make: *** [tcpserver] Error 1

The problem is the errno definition in error.h. The problem can be fixed with the following patch:
