Follow-up Comment #6:

Looking at old bug reports...

Except for graphics-props.cc, these files all define template functions and
are included in the corresponding header files to provide complete definitions
so that instantiation of the templates are possible.  The functions could also
just be provided inside the header files but that could make the header files
somewhat harder to understand.

In the GNU libstdc++ header files, these kinds of files use the extension
'.tcc' instead of '.cc' and the '.tcc' files are unconditionally included in
the corresponding header file (so <string> includes both <bits/basic_string.h>
and <bits/basic_string.tcc>).  In the '.tcc' file, there may be 'extern
template FOO<TYPE>' declarations for templates that are explicitly
instantiated elsewhere, presumably to help speed up compiling.  Maybe we could
do something similar?

The following change works for me to prevent graphics-props.cc from being
installed:

I'm closing this report as fixed.  I propose we discuss possible rearrangement
of header files elsewhere.
