Well.. glibc [does that](https://sourceware.org/git/?p=glibc.git;a=blob;f=bits/resource.h;h=6b83374331424da439ad0163e1e992d274847fc2;hb=HEAD#l80) (at least conditionally, in `!__USE_FILE_OFFSET64` mode).

Also the include order problem could be fixed by including rlim_t.h directly from this file (we already have a handful of files that do that).

Or even by doing nothing -- strictly speaking, you don't actually need the type to be defined at the point where you define the macro.

If that doesn't convince you, then I guess this is also fine :)
