I've offered to port those to Subversion some time ago. The idea was
rejected because then two separate build systems had to be maintained.

manifest resources tell Windows how to handle executables. There are
several different manifest resource types. For example:
Microsoft.Windows.Common-Controls manifest tells windows that the
application wants to use the version6 common controls (using the
XP/themed UI controls). If the manifest is missing, Windows will run the
application in 'old' mode where the controls are not themed.
Then there are manifests required so the application can use the new
C-Runtime dlls (the C-Runtime dlls for VS200X are installed in the WxS
folder, not the System32 folder anymore and therefore *require* the
manifest - otherwise the application can't load those dll's anymore).
And for Vista, there's also the 'UAC' manifest, which tells Vista that
the application is aware that it can't write to HKLM, the 'program
files', 'windows' or 'system32' folder. With that manifest, Vista will
reject any attempt to write to those. If the manifest is missing, Vista
will redirect those write accesses to the Vista virtual store so the
application can still 'run' (but read accesses still would go to the
original folder since only write access is redirected. which means an
application which stores its settings there, those settings will never
So yes, manifests are important and you have to properly include them.
Otherwise you'll run into big and hard to diagnose problems (especially
with if the uac manifest is missing).

The free VC-Express editions work just fine to compile Subversion (not
for TSVN though: we use MFC which is not included in the Express
edition). I've also had our NAnt script check for the VS version used
(VS2005 or VS2008) and do some version-specific stuff for each of those
versions - it's not that hard to implement something like that in NAnt.
(I've removed that again since we now require VS2008 due to the fact
that Vista icons (256x256 PNG) can't be used with VS2005)
