AFAIK, this behavior is allowed under ANSI C, since spaces
around identifiers does not change C semantics in any way.
Suggest you use ## for pasting colon to open.

That is, replace

	_machdep_sys_##x:;                  \

with

	_machdep_sys_##x##:;                \

Similarly, replace

    movl $(SYS_##x), %eax;          \

with

    movl $(SYS_##x##), %eax;          \

This'll work under gnu cpp.
