[syslinux] Get MEMDISK parameters from WinPE 32/64-bit?

[Shao Miller]

An initial, 32-bit, binary offering of a Windows MDiskChk is available at:

  Repository: git://git.zytor.com/users/sha0/syslinux.git
  Branch: mdiskchk_winbin
  File: win32/mdiskchk/exe/mdiskchk.exe

There are a few things to tidy up (mostly build process logic) before
submitting this for inclusion in Syslinux.

Does anyone know of a clever, Linux-distribution-independent way to find out
where MinGW has its lib/ and include/ dirs?  Right now, I've hard-coded the
path for Fedora 17 in the Makefiles.

Also: The 64-bit driver won't build under MinGW (WDK should be fine), so I
have to figure that out.

Please let me know how it works out, for you.  Thanks for your patience.
