Maybe I'm wrong--it isn't in the current documentation: -fglasgow- 
exts and -O both pipe through the mangler (driver/mangler/ghc- 
asm.lprl); -O implies -fvia-C as well (or it used to).

Ouch.  I meant /APP and /NO_APP (/ARGS do exist, but that's not what  
I meant).  Anyway, /APP and /NO_APP are GNU AS directives;  
essentially delimiters for comment blocks.  Under mingw, the mangler  
(ghc-asm.lprl:572) inserts:

/APP
/NO_APP

lines in between assembler code blocks.  (Honestly, these seem more  
like something AS would pass to the shell or cpp, not a directive.  I  
only know they exist because Yasm choked on it when I tested while  
giving ghc the '-fglasgow-exts' or '-O' options).
