... and not OS_CHROMEOS ?

Done.

+  DIR_SINGLE_EXTERNAL_EXTENSIONS,  // Directory for 'per-extension' definition
+                                   // files that describe extensions are to be
+                                   // installed when chrome is run.

I don't understand what this means (in the absence of the context provided by
the rest of this CL). What *is* 'single external extensions'? It also doesn't
sound grammatically correct (single extension*s* -- unless we're talking about
marital status, which we are not) :) It would seem to me that we might have
multiple extensions specified in the json file, no? I guess I'm trying to point
out that the word single is misleading in this context.

Also, it seems like the word 'which' is missing from the comments... (or
something).

Replaced by something that "sounded" better & better explanation (hopefully).

Missing:  // defined(OS_LINUX) && !defined(OS_CHROMEOS)

Since it is not something specified for other #defined "clauses", I am not sure
I would add it for this one just for the sake of consistency.

   DIR_EXTERNAL_EXTENSIONS,      // Directory where installer places .crx files.
 
   DIR_DEFAULT_APPS,             // Directory where installer places .crx files
