In the Gecko code we have a bunch of preprocessor conditions that help us conditionally compile code for specific platforms. These can get confusing so here is a handy-dandy table to help you keep them straight.

OS Windows OS X Linux-gtk Android iOS
Product Desktop Desktop Desktop Fennec GeckoView iOS
XP_WIN ✓       ??  
XP_DARWIN   ✓     ?? ✓
XP_MACOSX   ✓     ??  
XP_IOS         ?? ✓
XP_UNIX   ✓ ✓ ✓ ?? ✓
XP_LINUX     ✓ ✓ ??  
ANDROID       ✓ ??  
MOZ_WIDGET_GTK     ✓   ??  
MOZ_WIDGET_ANDROID       ✓ ??

Prefs files

Here is a similar table, but to see which prefs get used in which product:
