Subject: * ginsh_input(): Modern versions of flex want us to use the macro
X-Git-Tag: release_1-2-0~98
X-Git-Url: https://www.ginac.de/ginac.git//ginac.git?p=ginac.git;a=commitdiff_plain;h=5302957e34e8afadc5e9a13cede439cea843bbf7;ds=inline

* 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.)
