so they work better in AddUnique() and Remove().

From David Rothenberger:
- Added cyglink linker that uses Cygwin naming conventions for
shared libraries and automatically generates import libraries.

From Dirk Baechle:
- Update bootstrap.py so it can be used from any dir, to run
SCons from a source (non-installed) dir.

the --debug=count command-line option is used (2922).
- Added release_target_info() to File nodes, which helps to
reduce memory consumption in clean builds and update runs
of large projects.

- Improve Microsoft Visual Studio Solution generation, and fix
various errors in the generated solutions especially when using
MSVS_SCC_PROVIDER, and when generating multiple projects. The
construction variable MSVS_SCC_PROJECT_BASE_PATH, which never
worked properly, is removed. Users can use the new variable
MSVS_SCC_CONNECTION_ROOT instead if desired.

From Anatoly Techtonik:

- Use subprocess in bootstrap.py instead of os.execve to avoid
losing output control on Windows (http://bugs.python.org/issue9148)

- Revert patch for adding SCons to App Paths, because standard cmd
shell doesn't search there. This is confusing, because `scons` can
be executed from explorer, but fail to start from console.

- Fix broken installation with easy_install on Windows (issue 2051)
SCons traditionally installed in a way that allowed to run multiple
versions side by side. This custom logic was incompatible with
easy_install way of doing things.

utility is not found in PATH. Actual for Windows.

From Alexander Goomenyuk:

- Add .sx to assembly source scanner list so .sx files
get their header file dependencies detected.

without affecting the original construction environment's value.

From Rob Managan:

- Updated the TeX command strings to include a /D on Windows in
case the new directory is on a different drive letter.

- Fixed the LaTeX scanner so dependencies are found in commands that
are broken across lines with a comment or have embedded spaces.

by another program. Thanks to Hans-Martin von Gaudecker for
isolating the cause of this bug.
