Do we have any plans to un-flatten our header files?


Hi,

because I really dislike the hassle our (almost) flattened header
files cause quite often, I have made a very simple experiment to find
out how the header files really depend on each other.  Some results,
together with a dozen of short paragraphs of relevant text are here:

http://labs.suse.cz/mjambor/150417-headers_in_gcc/headers_in_gcc.html

Short summary: I wrote a script removing an include at a time and
parsing errors and recording such discovered "dependencies."  The page
has text-file reports showing what needs to be included before what,
in which files and because of which error messages.  I have also
plotted a few graphs from these "dependencies."  The pictures look
interesting, I am not sure if they are in any way useful, but have
a look and judge for yourself. 

Regardless of whether or not this experiment had any value.  Do we
plan to do un-flattening of header files in the course of the next
release or two?  The pain the flat header files is real and enduring
it for much longer or indefinitely seems unhealthy to me.

Thanks,

Martin
