Compile errors in map.cpp

[Mortow]

It's been quite a while since I have done a compile. I am using VS2017 and all builds succeed except Zone. I get three C3861 errors in map.cpp.

Description Project File Line
'InflateData': identifier not found zone map.cpp 999
'EstimateDeflateBuffer': identifier not found zone map.cpp 1055
'DeflateData': identifier not found zone map.cpp 1059

I have tried pulling a fresh clone from git but still come up with the same errors. Anyone have any ideas of what I might have going on?

Thanks,
Mortow
