That would break the ability to do stuff like:

#define BLAH(x,y)  mov r0, x; mov t1, y; bl foo

which is used widely within kernel and (iirc) glibc sources.  (You can't
embed newlines in the middle of preprocessor gunk.)  In fact, ';' was added
specifically so we could build the kernel with the GNU toolchain.
