The -A and --ansi switches are gone, together with the __STRICT_ANSI__

The -A and --ansi switches are gone, together with the __STRICT_ANSI__
predefined macro. Instead there is now a command line option --standard that
allows to set c89, c99 or cc65 as language standard. The compiler defines a
macro __CC65_STD__ that is one of __CC65_STD_C89__, __CC65_STD_C99__ or
__CC65_STD_CC65__ depending on the command line option. Default is cc65 (all
extensions) as before.
