Overview
Comment:Initialize variable pKeyDup in multiSelectOrderBy(). Technically it doesn't need to be initialized, but the reasoning required to come to that conclusion is too complicated for some automated systems. So it is initialized to keep some compilers happy. Ticket #3382. (CVS 5710)

Add test cases for ticket #3378 and #3381. Add a temporary hack to get those to problems fixed. The hack causes failures in alias.test, but those are much less serious than the aforementioned tickets. This is a stop-gap until we can figure out a proper fix.

Use (file nativename (pwd)) instead of just (pwd) to find the name of the current directory to pass to "PRAGMA temp_store_directory" in pragma.test. This helps the test pass on non-unix systems. (CVS 5709) check-in: 50feaa37 user: danielk1977 tags: trunk
