@code{GCC_INCLUDE_DIR} means the same thing for native and cross.  It is
9
where GCC stores its private include files, and also where GCC
10
stores the fixed include files.  A cross compiled GCC runs
11
@code{fixincludes} on the header files in @file{$(tooldir)/include}.
12
(If the cross compilation header files need to be fixed, they must be
13
installed before GCC is built.  If the cross compilation header files
14
are already suitable for GCC, nothing special need be done).
15
 
16
@code{GPLUSPLUS_INCLUDE_DIR} means the same thing for native and cross.  It
17
is where @command{g++} looks first for header files.  The C++ library
18
installs only target independent header files in that directory.
19
 
20
@code{LOCAL_INCLUDE_DIR} is used only by native compilers.  GCC
21
doesn't install anything there.  It is normally
22
@file{/usr/local/include}.  This is where local additions to a packaged
23
system should place header files.
24
 
25
@code{CROSS_INCLUDE_DIR} is used only by cross compilers.  GCC
26
doesn't install anything there.
27
 
28
@code{TOOL_INCLUDE_DIR} is used for both native and cross compilers.  It
29
is the place for other packages to install header files that GCC will
30
use.  For a cross-compiler, this is the equivalent of
31
@file{/usr/include}.  When you build a cross-compiler,
32
@code{fixincludes} processes any header files in this directory.
