Thanks! :)

$ grep SetupNativeCompilation * | wc
      68     215    5569

In CompileNativeLibraries there are 58, the rest are from demos, tools, etc.

And this is only the JDK; I'm not sure if or how many native libs the 
other projects are contributing...

I don't know. I might give it a try to group them just to see if it 
turns out to be a natural formation.

How do you mean? We like to only specify a directory per library, but 
unfortunately all too often the source is badly organised, so we have to 
resort to long lists. I can't see how this can be fixed short of a file 
restructuring process.

In my opinion, the current "mega file" stands out as worse. It is hard 
to navigate and modify. You just lose track of things, and it tends to 
make stuff duplicated, or that related stuff is not put together simply 
because it's impossible to get a grip on the whole file.

Just add a -r. :-) If you use a modern Linux, you can use "grep <val> * 
-r" -- I always forget to add the grep flags at the start, thankfully 
nowadays GNU grep accepts flags at the end.
