Build with vc142

[ncook-hxgn]

Hi there,

After digging around, I found windll\vc8\Unzip32.sln, but it won't build with Visual Studio 2019 16.7.3 or MSBuild 16.7 .. any chance of a vc142 solution?
(Or maybe I didn't find it yet?)

If it's as simple as copying windll\vc8 to windll\vc142, and performing the upgrade, I'm willing to create a PR.

E:\repos\NuGet\unzip>devenv windll\vc8\unzip32.sln

On doing a fairly mindless copy/paste/upgrade, I get the following errors when building the Static Release|Win32 config of unzip32.sln with Visual Studio 2019 16.7.3:

2>E:\repos\NuGet\unzip\extract.c(2182,36): error C2198: 'readbuf': too few arguments for call
2>E:\repos\NuGet\unzip\win32\win32.c(195,18): error C2373: '__p__pgmptr': redefinition; different type modifiers
2>C:\Program Files (x86)\Windows Kits\10\Include\10.0.19041.0\ucrt\stdlib.h(242): message : see declaration of '__p__pgmptr'

There are also a few warnings:

2>E:\repos\NuGet\unzip\extract.c(2195,50): warning C4133: 'function': incompatible types - from 'char *' to 'Uz_Globs *'
2>E:\repos\NuGet\unzip\extract.c(2195,53): warning C4047: 'function': 'char *' differs in levels of indirection from 'int'
2>E:\repos\NuGet\unzip\extract.c(2195,52): warning C4024: 'readbuf': different types for formal and actual parameter 2
2>E:\repos\NuGet\unzip\win32\win32.c(497,13): warning C4996: 'GetVersion': was declared deprecated

The final result:

Projects build report:
  Status    | Project [Config|platform]
 -----------|---------------------------------------------------------------------------------------------------
  Failed    | sfx\unzsfx32.vcxproj [Release|Win32]
  Failed    | dll\unz32dll.vcxproj [Static Release|Win32]

Possibly I will leave this the experts..
