Theoretically, possibly, you *could* get away with just the glibc 
headers. AFAIK there are no target executable binaries generated when 
providing the c++,objc,... compilers and libraries. However, I know 
only one way to obtain these glibc headers, and that is to _build_
glibc. :-)

Maybe you could experiment with glibc's configure and Makefile stuff, 
possibly there even is a "make install-headers", but I doubt it is 
that easy. Since glibc uses an elaborate directory overlay system to 
get to the final set of .c and .h files for a specific platform, it is 
not very easy to extract only the headers as it is with the Linux 
kernel, for instance.
