Isn't the argument to #line a C string literal in which one would expect 
backslashes to be escaped? If not, how would it show a filename 
containing a '"' character?
   [andrew@emma inst.92.5701]$ bin/ecpg x\\\"a/y.pgc   [andrew@emma inst.92.5701]$ grep line  x\\\"a/y.c   #line 1
"x\"a/y.pgc"

This must surely be wrong.
