This looks strange to me. vcbuild/include/poll.h will only prevent the
correct header from being included, while compiling an linking against
compat/win32/poll.[co]... That seems dangerous to me, because the
interface might be declared differently.

Instead, I think compat/vcbuild/include/poll.h should be removed, and
_WIN32_WINNT set to a value below 0x600. That way the poll-stuff
doesn't get pulled in by winsock2.h (as it's Vista and above only).

This was already discussed in your "[PATCHv2] Compile fix for MSVC" thread:
http://mid.gmane.org/CABPQNSaCRRRpEQPG1Mb4DovkMdQSBhHTm-i7y5M4iT+ndHX4XA@xxxxxxxxxxxxxx

Here's the patch that fixes it. I still can't build Junio's master,
due to sys/resource.h missing. This comes from ebae9ff ("compat: add
missing #include <sys/resource.h>"), and is only guarded against
MinGW, not MSVC...
