A concise explantion of why it won't be happening at this point:
Which version do I choose?
If you are using PHP with Apache 1 or Apache2 from apache.org you need to use the VC6 versions of PHP
If you are using PHP with IIS you should use the VC9 versions of PHP
VC6 Versions are compiled with the legacy Visual Studio 6 compiler
VC9 Versions are compiled with the Visual Studio 2008 compiler and have improvements in performance and stability. The VC9 versions require you to have the Microsoft 2008 C++ Runtime (x86) or the Microsoft 2008 C++ Runtime (x64) installed
Do NOT use VC9 version with apache.org binaries http://windows.php.net/download
In other words, Visual C 2008 binaries work with IIS, not with Apache.org distributed binaries. XAMMP uses the apache.org binaries, thus no Imagick without recompiling Apache with the same compiler, probably ditto on PHP (although I am unsure on this part).
Note also that installing the runtimes (which would now likely be needed for Apache as well) would break the level of portability in XAMPP.
