Two reasons (both may be totally inadequate!):

1. Because if you do a standard (i.e. non-cross) install of gcc, this is 
where these headers reside.

2. Because I have some software (badly written maybe: I can't say, it's not 
mine, but I didn't want to name names!) that I need to cross-compile that 
expects to find and makes direct reference to a usr/include/c++/... folder. 
In most other scenarios I guess users of this particular software find 
themselves in (e.g. local build or even crosstool before all these changes), 
it works without problems; but with the current position crosstool is in, it 
balks.  Yes, I know that the c++ compiler holds the location of these 
include files so it can "always" find them, but in this case its broken.

Isn't that what crosstool is supposed to be doing for me?  Or am I 
misunderstanding you?
