+SYNOPSIS
+ void runtime_error(string err, string prg, string curobj, int line)
+
+DESCRIPTION
+ This function has to announce a runtime error to the active
+ user. If the user has enough privileges, it might give him the
+ full error message together with the source line. Else it
+ should issue a decent message ("Your sensitive mind notices a
+ wrongness in the fabric of space").
+
+ Note that prg denotes the program actually executed (which
+ might be an inherited one) whereas curobj is just the
+ offending object.
