troubles building GNU netcat on HPUX 11.23

[Sergey Akifiev_1]

i've got error when building gnu netcat-0.7.1 on
sergey@host:~/src/netcat-0.7.1$ uname -a
HP-UX host B.11.23 U ia64 1543514247 unlimited-user license

`./configure' step whent perfectly, but when doing `make' it bombs out with:
gcc -DLOCALEDIR=\"\/usr/local/share/locale\" -DHAVE_CONFIG_H -I. -I. -I.. -I../lib/contrib -g -O2 -Wall -c `test -f 'udphelper.c' || echo './'`udphelper.c

i have gcc-4.1.1 installed from depot obtained from http://hpux.connectisl.com/.
google pointed me to a gcc mailing list, which said, that it is incompartibility of HPUX system headers and gcc4.
so how do i build this tool?
thanks in advance.
PS. i cannot achieve succes with /usr/bin/cc either.

P.S. This thread has been moved from General to HP-UX > languages. - Hp Forum Moderator

The patch below works for me, HPUX behaves poorly when it comes to the lifconf macros.
