You should use gcc 4.1. Apr, apr-util and expat build out-of-the-box
if you use svn trunk for apr and apr-util and expat official release
2.0.0. gcc 4.1 supports wchar_t and makes building log4cxx easy.

Yes, it's not easy to build apr-1.2.7 with mingw 3.x series. Using svn
trunk and gcc 4.x is much easier.

Well, that's up to you, none of it is necessary if you use trunk and gcc

I'm my own program just fine. However, what's the command to run the
unit tests for apr? I'll try that out.

Yes, but it took hours for me to compile gcc 4.x. If you are going to
try it, let me know, I'll send you the configure && make options I used.
I can even upload the binary I have, it may work for you.

It would be possible for me to do builds of log4cxx with mingw every now
and then, especially before official releases. Is there a place where
beta's are announced, so that this can be done before official releases?
