[plt-scheme] Building Mzscheme 352

I can build libmzgc. But while building libmzsch, I get

mz-352-src-win\plt\src\mzscheme\include\../sconfig.h(22) : fatal error
C1083: Cannot open include file: 'mzconfig.h': No such file or directory


Since I found a mzconfig.h.in file in mz-352-src-win\plt\src\mzscheme, I
renamed the file as 'mzconfig.h' and  added its path to the project
additional include dirs. In this case I can compile (despite a handful of
warnings), but not link because of:

Creating library ..\..\..\lib\msvc\libmzschxxxxxxx.lib and object
.\..\..\lib\msvc\libmzschxxxxxxx.exp network.obj : error LNK2019:
unresolved external symbol _hstrerror referenced in function
_mz_gai_strerror


Can you help, please?
