I added an "#if !defined" around the #define in apr.hw.
I also replaced their #pragma warning (which is indicated as their
solution to the 'POSIX name deprecated' warning) with a similar
#if/#define/#endif for _CRT_NONSTDC_NO_DEPRECATE, although I'm not sure
that that's needed (thy may have had a specific reason for using the
#pragma instead).

That's what I thought too - apr.h even duplicates the #define and
there's no compiler warning from that, only for the first one.
As it turns out, the /D command line option of the compiler is
documented as defaulting to a value of 1.
So the predefinition in the project file is
 #define FOO 1
while apr.h uses
 #define FOO
so the definition isn't identical.
Perhaps using _CRT_SECURE_NO_DEPRECATE= (with the added '=') in the list
of additional preprocessor defines of the subversion projects also
makes the warnings go away - I'll check when I get home from work

I'm a bit hesitant to install VC6 on my machine, but I'll see what I
can do. VC6 also post-build rules and predefined vars, so I doubt the
rule will differ substantially.

I only have 2 reasons for not using swig:
 - I have absolutely no experience with swig
 - from what I can tell, it maps everything directly to static functions
   of a class, with no name changes. This makes it fit in very badly
   with other .NET class libraries (naming conventions, etc.)
But I'll look into it.
