[Bug 790046] [NEW] cgraph.h includes cdt.h as <cdt.h>, shoudl it not be "cdt.h" or <graphviz/cdt.h>?

[pliz]

Public bug reported:

Binary package hint: libgraphviz-dev

Hi guys,
Please, explain if this is not a bug. The file /usr/include/graphviz/cgraph.h contains the following line:
#include                <cdt.h>
When I try to compile anything that includes this file (cgraph.h), gives me an error. For example
// start file test.c
#include <graphviz/cdt.h>
#include <graphviz/cgraph.h>
// end file test.c
Compile as:
gcc -lcgraph testcgraph.c 
In file included from testcgraph.c:2:
/usr/include/graphviz/cgraph.h:20:18: error: cdt.h: No such file or directory

Should not the include line be changed to <graphviz/cdt.h> or "cdt.h",
which would not have this problem?
