I can confirm that tolerance for this isn't universal.  "cc" on Digital
UNIX 4.0 won't recognize indented #if either, just as reported above.
It isn't portable.

BTW, it has been some years since I used HPUX 10.20, but at the time
we used "cc" for most everything, usually with "-Ae" to support modern
C usage.
