/*
 * Package for checking and catching common errors, printing out
 * errors nicely, etc.
 *
 * 6/01/95  Paul Placeway  CMU speech group
 *
 * 6/02/95  Eric Thayer
 *	- Removed non-ANSI expresssions.  I don't know of any non-ANSI
 *		holdouts left anymore. (DEC using -std1, HP using -Aa,
 *		Sun using gcc or acc.)
 *      - Removed the automatic newline at the end of the error message
 *	  as that all S3 error messages have one in them now.
 *	- Added an error message option that does a perror() call.
