/*
 * Using unmodified gcc-1.36, config.gcc {sun3,sun4-os4}:
 *
 * This program causes cc1 to generate a signal 10 (or 11) when
 * compiled with both the options -Wswitch and -traditional.
 * If c has any type other than `unsigned char' or 'unsigned char *'
 * gcc runs fine.  GNU regex.c (in sed-1.06) has code like this.
 *
 * A suggestion to people using gcc: 
 * create an executable named gcc with the 2 lines:
 *       #!/bin/sh
 *       /p/bin/gcc -Wswitch "$@"
 * where you'd replace /p/bin/gcc with the absolute pathname of the
 * binary executable on your system.  Then put this gcc in a directory
 * that precedes (in your $PATH) that of the binary.
