Oh, nice, I didn't know about this convenient notation for default args
in tcl, and the one I knew about I found too cumbersome. Thanks for the
tip, I put it in the patch below.

And this too.

'zactly my thinking.
Here's what I'm testing (same way). Ok to install if it passes?
libstdc++: testsuite: conditionalize symlink tests
From: Alexandre Oliva <ol...@adacore.com>
Several filesystem tests expect to be able to create symlinks even
when !defined (_GLIBCXX_HAVE_SYMLINK), and fail predictably, reducing
the amount of testing of other filesystem features.
They are already skipped for mingw targets. I've extended the
skipping to other targets in which _GLIBCXX_HAVE_SYMLINK is undefined,
through a new NO_SYMLINKS macro in testsuite_fs.h that guards
skippable portions of tests, and dg-require-target-fs-symlinks for
tests that would be reduced to nothing.
for libstdc++-v3/ChangeLog
* testsuite/util/testsuite_fs.h (NO_SYMLINKS): Define on
mingw and when create_symlink is a dummy.
* testsuite/27_io/filesystem/operations/symlink_status.cc:
Drop mingw xfail.
(test01, test02): Don't create symlinks when NO_SYMLINKS is
defined.
* testsuite/27_io/filesystem/operations/canonical.cc (test03):
Likewise.
* testsuite/27_io/filesystem/operations/copy.cc (test02):
Likewise.
* testsuite/27_io/filesystem/operations/create_directories.cc
(test04): Likewise.
* testsuite/27_io/filesystem/operations/create_directory.cc
(test01): Likewise.
* testsuite/27_io/filesystem/operations/permissions.cc
(test03, test04): Likewise.
* testsuite/27_io/filesystem/operations/remove.cc (test01):
Likewise.
* testsuite/27_io/filesystem/operations/remove_all.cc (test01):
Likewise.
* testsuite/27_io/filesystem/operations/rename.cc
(test_symlinks): Likewise.
* testsuite/27_io/filesystem/operations/weakly_canonical.cc
(test01): Likewise.
*
testsuite/experimental/filesystem/iterators/recursive_directory_itreator.cc
(test06): Likewise.
* testsuite/experimental/filesystem/operations/copy.cc
(test01): Likewise.

(test01): Likewise.
* testsuite/experimental/filesystem/operations/rename.cc
(test01): Likewise.
* testsuite/lib/libstdc++.exp
(v3_check_preprocessor_condition): Add optional inc parameter.
Add it to the test program after include bits/c++config.h.
(check_v3_target_fs_symlinks): New.
* testsuite/lib/dg-options.exp
(dg-require-target-fs-symlinks): New.
* testsuite/27_io/filesystem/operations/read_symlink.cc:
Replace mingw xfail with require target-fs-symlinks.
* testsuite/experimental/filesystem/operations/read_symlink.cc:
Likewise.
