Error building Postgres for Windows

[Stephan Sandow <ssandow@xxxxxxx>]

Hello,

i get 3 errors building the postgres server Version 12.0 for windows:

 plperl.obj : error LNK2019: unresolved external symbol "new_ctype" in 
Function "plperl_init_interp
". [C:\postgre_src\postgresql-12.0\plperl.vcxproj]
  plperl.obj : error LNK2019: unresolved external symbol "new_collate" 
in Function "plperl_init_inte
rp". [C:\postgre_src\postgresql-12.0\plperl.vcxproj]
  plperl.obj : error LNK2019: unresolved external symbol "new_numeric" 
in Function "plperl_init_inte
rp". [C:\postgre_src\postgresql-12.0\plperl.vcxproj]
  .\Release\plperl\plperl.dll : fatal error LNK1120: 3 nicht aufgelöste 
Externe [C:\postgre_src\postgresql-12.0\plperl.
vcxproj]

My config.pl:
$config->{perl} = 'C:\Perl64';

There is Active Perl 5.28

Iam using the x64 Native Tools Command Prompt from Visual Studio 2019

Any help would be greatly appreciated.
