        * include/Makefile.am:  New file encapsulating header generation rules.
        * Makefile.am (SUBDIRS):  Prepend 'include' directory.
        * acinclude.m4:  Moved/removed rules for building various headers.
        * configure.in (AC_OUTPUT):  Add include/Makefile.
        * mkc++config:  Removed.

Introduced a configury problem. libstdc++-v3 fails to build if you configure with a relative path to the source, like
../gcc/configure 

The symlinks should be created with absolute paths.
