Libvirt compilation failure under mingw32

[Adam Huffman]

Today I've been trying to compile libvirt 0.7.0 under mingw32 on a 
Fedora 10 box.

After installing portablexdr from the review request, I got much 
further.  However, compilation fails during the tests:

make[3]: Entering directory `/newhome/adam/Build/libvirt-0.7.0/tests'

make[1]: *** [all-recursive] Error 1

Is this expected?  Am I missing another package not yet in Fedora?
