Make public headers work with gcc -Wundef
The C standard allows undefined symbols in #if statements, giving them
the value 0 (C99 section 6.10.1). However, some software builds with
gcc -Wundef, which issues a warning on undefined symbols in
preprocessor expressions. Make the public headers safe for that
environment by using #ifdef instead of #if for TARGET_OS_MAC.
