I'd ignore that, except that machine language non-C biased people may say something ruder :-) 'Designed for C' improves it for C use(hopefully), but almost certainly hardly affects its suitability for using assembler. (I'm not advocating use of assembler in this context - just noting that some may find the comment challengeable :-) ).
