Building xgen for AIX

[J H Mintz]

I am attempting to build XGEN to run under AIX whcih is using X-windows version 3.
On running make after the setup procedure, the follwoing message was displayed:
make
        cc -O -DSYSV  -I.  -c addnode.c
Processing include file /usr/include/sys/signal.h
 63    83 | #define SIGCHLD   20    /* (+) sent to parent on child stop or exit 
            */
    1506-236: (W) Macro name SIGCHLD has been redefined.
Processing include file ./xgen.h

It appeared that on our system the 2 include filed mentioned were
in X11 rather than Xm so I changed the source of Xgen.h to reflect
this.Unfortunately, on re-executing make, I still got the syntax error-17 % make
        cc -O -DSYSV  -I. -I/usr/local/X11R4/include  -c addnode.c
Processing include file /usr/include/sys/signal.h
 63    83 | #define SIGCHLD   20    /* (+) sent to parent on child stop or exit 
            */

a - 1506-046: (S) Syntax error.
make: 1254-004 The error code from the last command is 1.

Does anyone have any experience of setting up Xgen under AIX and 
any help with the above problem?
