You're right, this is a compatibility bug.  I'll work on fixing this for 
the next Yasm release, but in the meantime you could use the preprocessor 
to detect which assembler is being used (from looking for the 
assembler-specific version defines) and change between the forms, e.g.

%ifdef __NASM_MAJOR__
section .note.GNU-stack
%else
section ".note.GNU-stack"
%endif

(or alternatively check for one of the Yasm defines such as 
__YASM_MAJOR__)
