problems with xgraph

[Insung Jung <dormouse@cherry.soongsil.ac.kr>]

Dear sir.

I have a problem with building xgraph as follows.

-------------------------------

#144 cherry:/root/ns/xgraph%xmkmf

mv -f Makefile Makefile.bak
imake -DUseInstalled -I/usr/local/X11R6.3/lib/X11/config

#145 cherry:/root/ns/xgraph%make

gcc -O2   -I/usr/local/X11R6.3/include  -Dsun -DSVR4  -c  xgraph.c
In file included from xgraph.c:23:
xgraph.h:163: conflicting types for `sprintf'
/usr/include/stdio.h:177: previous declaration of `sprintf'
xgraph.c: In function `main':
xgraph.c:109: warning: passing arg 1 of `XSetErrorHandler' from
incompatible pointer type
xgraph.c: At top level:
xgraph.c:699: warning: type mismatch with previous implicit declaration
xgraph.c:645: warning: previous implicit declaration of `NewWindow'
xgraph.c:699: warning: `NewWindow' was previously implicitly declared to
return `int'

-------------------------------------------------

To solve the above problem, I have already been applied the following
patch to Imakefile, xgraph.h as described at
http://www-mash.cs.berkeley.edu/ns/ns-problems.html

----------------------------------------

How can i fix ? Is it possible ?
My configuration is as follows

-----------------
Workstation : Sun, Ultra 1/140
OS : Solaris 2.5.1
X  : X11 6.3

Your helps are really appreciated.
