🚀 go-pugleaf

The message:
		 `#pragma implementation' can only appear at top-level

is generated if the #pragma appears after a #line.  That makes sense
most of the time, but is causing me some problems now because I want to
put the pragma in the declaration section of bison deck.  Bison puts a
#line control right at the top of the file.

Of course, I can run bison -l and suppress all the #lines, but this
makes the compiler messages more confusing.

Since bison already has all the #ifdef __cplusplus conditionals in the
parser, I figured somebody might have run into this before and have a
suggestion.  Other than this, bison output seems to work fine with
c++.
