/* This file is exactly like compiler.c.  I could just use compiler.c if
   I could be sure that every C++ compiler accepted extensions of ".c".  */

/* Note the semicolon at the end of this line.  Older versions of
   hp c++ have a bug in string preprocessing: if the last token on a
   line is a string, then the preprocessor concatenates the next line
   onto the current line and eats the newline!  That messes up TCL of
   course.  That happens with HP aC++ A.03.13, but it no longer happens
   with HP aC++ A.03.45. */
