Don't worry!  You have done the right thing.  If you want you can write conditional code, but that is at your discretion.

I used it to fix a nonworking driver for a pctel winmodem

and got a big thanks by finding these changes so that the driver could compile.  The conditional code was incorporated and some warnings were fixed(code was cleaned up).
