Just a heads-up regarding issue #3.

Hm, doesn't
27_io/basic_filebuf/sputbackc/char/9425.cc
test something like that, or at leas EOF after?  It doesn't fail for you?

It does for me (cris-axis-elf), seen as a regression with a fixed simulator.
Or maybe that's not the reason?  Ok, I'll look closer.

FWIW, due to <http://subversion.tigris.org/issues/show_bug.cgi?id=2333>
I also saw 27_io/basic_filebuf/sync/wchar_t/1.cc (a file removed in r164529) as
regressing, which had me confused until I STFW and found that svn up to 1.7.0
(version according to the bug report, but I can confirm it includes 1.6.9) did
not include (files in) deleted directories in diffs, like "svn diff -c164529".
Note that sync/char/1.cc is included.

Looks like lots of libstdc++ file I/O test-cases are missing "// {
dg-require-fileio "" }" lines.  I'll add them as obvious.
