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. git-svn-id: svn://svn.cc65.org/cc65/trunk@3133 b7a2c559-68d2-44c3-8de9-860c34a00d81
