In 'Cygnus' GCC, this definition is considered a 'non-const' pointer to a 'const'
bunch of bytes, i.e. you can point to it, but you can't modify this contents.

You can define 'char string1[]="foobar"' to avoid this behaviour.

DJGPP (with the aproppiate compiler options) warn this, but IIRC, 'Cygnus' not.
