Actually that's not the reason.  The two reasons are:

1. line endings; msvc and msdev studio hate several files with unix line endings
   and either fail all together (nmake makefile) or produce erroneous results
   (emitted diagnostic line numbers from .c source files etc.)  The win32 package
   uses srclib/apr/build/lineends.pl to mop text files from one to the other form.
   Unless you are using a linux toolchain, or working on a volume that supports
   two views of the same file (e.g. Cygwin 'DOS' mounted unix volumes) this
   issue seems that it would continue to plague you.

2. build files; this shouldn't be a hassle for you, it simply includes generated
   win32 exported makefiles and makefile dependencies from .pdb projects, 
   along with the awk result .rc version files.  These aren't present in the
   Unix build, and are honestly not required to build the project if you use
   Visual Studio later than version 5.

>Can someone tell me why the --shadow option was removed?

Not I - other than we ditched our over-abused configure script in favor of
autoconf's inherent features.  As you suggest, --srcdir does the same thing.
