Update of /home/cvs/GiNaC/ginsh

Modified Files:
	ginsh_lexer.ll 
Log Message:
* ginsh_input(): Modern versions of flex want us to use the macro
  YY_CURRENT_BUFFER instead of accessing yy_current_buffer directly.
  (I'm not sure about the preprocessor conditional, but asking whether
  YY_CURRENT_BUFFER is defined appears to be the most natural strategy.)
