To save a couple of clicks:
"C:\projects\postgresql\pageinspect.vcxproj" (default target) (56) ->
(Link target) ->
  heapfuncs.obj : error LNK2001: unresolved external symbol
  pg_popcount32 [C:\projects\postgresql\pageinspect.vcxproj]
    .\Release\pageinspect\pageinspect.dll : fatal error LNK1120: 1
    unresolved externals [C:\projects\postgresql\pageinspect.vcxproj]

I think that it would be more simple to just use pg_popcount().
That's what other contrib modules do (for example ltree or intarray).
