Since 2.1.99-test5, pciutils should also be compilable on Windows.

However, you need to configure the package manually:

lib/config.mk:

PCI_ARCH_I386=1
PCI_HAVE_PM_INTEL_CONF=1 
PCI_OS_WINDOWS=1 

lib/config.h:

#define PCI_ARCH_I386
#define PCI_OS_WINDOWS
#define PCI_HAVE_PM_INTEL_CONF
#define PCI_PATH_IDS "pci.ids"
#define PCILIB_VERSION "2.1.99-test5"
