Yes, you are right.  Headers are not libraries.  I did not mean to
imply otherwise. Those are the newer C++ified versions of the
*headers* for for the standard C++ library... and additionally...

as every C++ programmer knows, the C++ standard library does in fact
include C with few exceptions.

If I wanted to program stricly C in DOS, there are many such
implementations that will do this, including Borland PowerPackforDOS,
Turbo C++,  and Pacific C.

What is special about DJGPP to me is that it can build as a target for
gcc on a linux host.  So of course my question refers to C++ and not
C.

This is why I asked this question in this fashion:

"Isn't the standard library (along with all of the non-deprecated
header and STL files for ANSI / ISO C++) supposed to build with the
crossgcc build?"

I guess now that I think about it, I could have been more clear and
asked it this way:

Isn't the ANSI / ISO C++ Standard Libray ( libstdc++ ) along with its
headers (non-deprecated or 'C++ified' headers and STL headers)
supposed to build with the linux hosts crossgcc.

I ask it this way because several years ago, there were C++
implementations that did not have STL support and used what is now
considered to be deprecated headers. 

I just want to be clear that I will be able to build a cross gcc that
makes DOS executables with the same full C++ support that a natively
built GCC-3.2 can do. 

I believe that the answer is yes, but I just wanted to hear somebody
say it so I could decide whether or not to keep trying to get this to
work.  I am stubborn, so I will continue to assume that it will work,
so I will keep trying :)

I tried linking against them and it didn't work.

Yes, this is what I am doing in between posting and e-mailing for
help.  Any chance to get help is preferred so I do not waste time or
possibly fail where another may have succeeded.   :)

Many thanks for your help and replies, Hans-Bernhard. 
Once I work through this I will gladly post the final recipe.
