This looks like a bug in the particular bison version you have.  I 
haven't seen this issue.

I'm using bison 2.4.1 and flex 2.5.35 on my MSVC builds.  And bison 
3.0.2 on Linux.  AFAICT, all generated program_parse.tab.c I've seen 
don't rely on __attribute__ for non-GNU compilers.

Which bison/flex version did you use?

Thanks.  I pushed this change.
