I will. First and formost I wanted to get the results of my work
somewhere safe ;)

There have been mainly four issues (some apply to TSVN as well):
* the Windows *platform* is identified by _WIN32 not WIN32
* with VC++, sizeof(long)==sizeof(int)==4, even on a 64 bit platform
  (some pointer casts therefore caused access violations in debug mode)
* MS considers C standard lib functions like strcpy() unsafe and
  has them marked as deprecated. Additional settings are required
  to get rid of that "noise".
* SVN's generator for VS projects does not yet support VC8.0 projects
  and platforms other than Win32 out of the box

The above mentioned plus:
* GRETA does not work on CHAR* anymore (out of the box) since string
  iterators are no longer implicitly convertible to pointers
* DBTYPE in BDB\db.h conflicts with a definition deep in the oledb headers
  (trying to exclude the latter produced inconsistent vtables - yuck!)
* loop header declarations belong to the loop's scope
  (implemented since 7.0, now forced)

BTW, one sweet thing about VS2k5: parallel builds. Just works.

Done.

*tryingNotToOvercommit* O.k. as soon as there is a decently working
64 port, yes, I volunteer. However, we are still far from that point and the
effort I may spend to get there is limited.
