   6 /* This file creates the getbuildinfo.o object, by first
   7    invoking subwcrev.exe (if found), and then invoking cl.exe.
   8    As a side effect, it might generate PCBuild\getbuildinfo2.c
   9    also. If this isn't a subversion checkout, or subwcrev isn't
  10    found, it compiles ..\\Modules\\getbuildinfo.c instead.
  11
  12    Currently, subwcrev.exe is found from the registry entries
  13    of TortoiseSVN.
  14
  15    No attempt is made to place getbuildinfo.o into the proper
  16    binary directory. This isn't necessary, as this tool is
  17    invoked as a pre-link step for pythoncore, so that overwrites
  18    any previous getbuildinfo.o.
