        * include/Makefile.am (install-data-local): Remove pch-install rules.
        (host_headers): Add stdc++.h, stdtr1c++.h, extc++.h.
        * include/Makefile.in: Regenerate.
        * config.h.in: Same.

        * scripts/check_compile: Remove space between outputs.  
        * include/ext/throw_allocator.h: Correct doxygen markup.        
        * include/bits/char_traits.h: Correct spacing.
        * include/bits/stl_function.h: Same, for 80 column.
        * include/std/valarray: Same.
        * testsuite/util/testsuite_iterators.h: Same.   
        * testsuite/25_algorithms/headers/algorithm/synopsis.cc: Format.

breaks the build when the source tree is not modifiable:

Making all in include
touch: cannot touch `./i686-pc-linux-gnu/bits/stdc++.h': Permission denied
make[4]: *** [i686-pc-linux-gnu/bits/stdc++.h.gch/O2g.gch] Error 1
make[3]: *** [all-recursive] Error 1
make[2]: *** [all] Error 2
make[1]: *** [all-target-libstdc++-v3] Error 2
make: *** [all] Error 2

It is obviously wrong to touch a symlink to a file in the source tree - if the
file (other than in 4.2.x) really needs to have full contents, then it needs to
be copied (with ownership and permissions changed) rather than symlinked.
