pC++ error message

I was compiling a file starting with  

#include <sys/times.h>
#include <sys/types.h>
#include <sys/resource.h>

, on caledonia.cs.indiana.edu.
The pc++ compiler said:

/u/beckman/sage/bin/iris4d/pc++ -w -O -D_SMRTS_ -D__SGIMP__ -mips4 -64  -o temp.C -I. -I/u/beckman/sage/h -I/u/beckman/sage/target/include -I/u/beckman/sage/target/sgimp/include  main.pc
WARNING: internal comment state machine error.
line = 124, file = /usr/include/sys/resource.h  please report bug

So I do.

(Now I expect some people to say that no, you can't use [most of]
standard include files with pC++, and they probably are right;
but I am not arguing about this now.)
