Hi. You had a problem with an 'schain botch' when you compiled a C
program. This error indicates a bug in the compiler you were using.
Would you please mail a report of this to 'bugs'? Be sure to include
the compiler you were using, the workstation type, and the athena
release, as well as much information about your code as necessary in
order that the people responsible for the compiler can isolate the bug.

Ok, here's the report. I'm coding a graphics editor using HP widgets,
X11R3, on a VAX2000 in the student center. When i compile
with gcc in this manner:
/mit/gnu/vaxbin/gcc -I. -L/mit/neur/Xhp/lib draw.c -lXw -lXmu -lXt -lX11
the program compiles and runs.(no XtNresize redefined either)
Originally i tried cc in the same manner and I get this:
./Xw/Xw.h: 584: XtNresize redefined
"draw.c", line 213: compiler error: schain botch
Line 213 is:
XSetTile(dpy,data->gc,tile);
but I don't think that has a problem since the error
"floats" to other lines, depending on what i comment out.
Here is the function in total that includes the line 213
One of the OLC members sent me a bug report saying that
perhaps, a void decalration is the problem. Article 3012
of Athena bugs discuss group. Any confirmation would be helpful
Thanks,
John Travis
