I do not know what their longterm intentions are.  Currently what you say is 
quite true.  

cat /download/com/trolltech/qt-4-snapshot/include/QtGui/QWidget
#include "qwidget.h"

Nonetheless, There is still the problem of identifying the wrapper files as 
C++ source files.  For example, how do I retrieve a list of all the available 
headers using find?  After I sent my wishlist, I added a few more items.  
That last is header file name completion in #include directives.  Now, if it 
were just Qt, and just KDevelop, there would be little problem in so much as 
a custom solution for the particular situation could be implemented.  But 
KDevelop is not the only tool I use, and Qt is not the only library I use.  
Since this list is about KDevelop, and not the other development tools I use 
((X)Emacs in particular), I will focus on the KDevelop side of things.  

I'm working with another library that uses extensionless headers, and these 
most certainly are NOT wrappers around .h files.  Notice that the web server 
is not serving these files out as a known type.

My current approach to building the PCS is to copy every header file to a new 
location and give it a .h extension.  There are probably polite words used to 
describe the approach, but I can't think of any.
