I think these end up (on non-gcc compilers; it uses a gcc extension for
gcc) expanding to something like:

(do { ... } while(0);}) 

(where the ... is whatever it actually does to set the flag bit) are the
enclosing parentheses legal in C?  YOu might find that just redefining
the macros without the ( and ) surrounding it will work.
