[RFC] Header organization of -base & -gui

[David Ayers]

Hello,

currently when installing -base and -gui you will find some of the 
gnustep specific headers in the Headers/Foundation and Headers/AppKit 
directories, when installing with non-apple-apple-apple configuration.  
If your code relies on these headers, you currently would include them like:

#include <Foundation/GSMime.h>

Yet when installing -baseadd with apple-apple-apple, I suspect these 
headers were installed in gnustep/base therefor requiering something like:

#ifndef NeXT_Foundation_LIBRARY
#include <Foundation/GSMime.h>
#else
#include <gnustep/base/GSMime.h>
#endif

I'm planning to fix this for the next release.  As of then for all 
gnustep specific headers, your code should be updated to:

#include <gnustep/base/GSBaseSpecificHeader.h>
#include <gnustep/gui/GSGuiSpecificHeader.h>

In the next release there still will be dummy headers in Foundation and 
AppKit that emit a warning and then include the header from the new 
location, to ease updating.

Please let us know if you have concerns about this change.

Cheers,
David
