Hi,
As far as I can see, PCL trunk has been in uncompilable state (for Windows) for quite a while now (
check here). Depending on whether you are on 32-bit or 64-bit I would suggest you to update (for example) to revision 6768 or 6782 respectively. They both seem to compile, though fail some tests. If you do not need the very latest trunk, pick "the last successful build" from the aforementioned site.
Regards,
Sergey
