Ok, I know I just snipped off your whole list of replies but it was
getting a bit long...  As far as I understand what you're asking - you
want to know how to make Dev C++ use the new header files associated with
GCC v3.3.1 right?

In Dev-C++ go to "Tools" then "Compiler Options" then "C++ Includes"

There you'll see a list of where Dev-C++ looks for its include files. 
When you download an updated version of GCC, if you look you'll find that
the tar.gz file has a directory tree like this:

bin/
include/
include/c++
include/c++/3.3.1
include/c++/3.3.1/backward
include/c++/3.3.1/bits
include/c++/3.3.1/ext
include/c++/3.3.1/mingw32
include/c++/3.3.1/mingw32/bits
lib/
man/
man/man1

You'll see this is VERY similar to how Dev-C++ is organized.  In fact, if
you decompress the tar.gz file of GCC v3.3.1 over Dev-C++'s directory
structure, you'll find that all you need to do to make things work is the
following:

Add the above directories to your includes list (above the default ones
so it looks there first):

include/c++/3.3.1
include/c++/3.3.1/backward
include/c++/3.3.1/mingw32

This will make Dev-C++ look in the NEW directories for include files
first (thus using new versions, if any) and if it can't find them there,
it'll default to the older ones.

Now, change to "Binaries" list of directories and add the following:
lib/gcc-lib/mingw32/3.3.3

Right above the similar entries (probably lib/gcc-lib/mingw32/3.2 or
lib/gcc-lib/mingw32/3.1).

Once more, don't remove the old entry incase it can't find something
it'll have default to look into.

I found some of the C includes not with the G++ tar.gz file but with the
GCC Core download, in which they were in:
lib\gcc-lib\mingw32\3.3.1\include

I would assume that if you felt you needed them, you could add this
directory to to "C Includes" then you'd need to add the entry:
lib/gcc-lib/mingw32/3.3.1/include

Right above the one:
include/

I hope that helps.
