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.
