xinetd 'make' errors

[Brian Amstutz]

I'm trying to install xinetd (v2.3.9) on HP-UX 11.0. When I do a make, I receive the following errors:
# make
cd libs/src/portable ; make CC=cc CFLAGS='-g -I../../include' install
make[1]: Entering directory
`/usr/local/xinetd/xinetd-2.3.9/libs/src/portable'
cc -g -I../../include -c fake-getnameinfo.c -o fake-getnameinfo.o
cc: "/usr/include/sys/socket.h", line 171: error 1000: Unexpected symbol:"unsigned".

I'm a little puzzled by this since I know there are other programs that user (e.g. ssh) that compile OK. Do I need to add something in the configuration that tells the compiler that "unsigned" variables are valid?

Thanks!
