Cause found.

How it worked before
1. Call link from menu Visual Studio 2019: Auxiliary\Build\vcvars64.bat
    That create a console with settings to compile on 64 bits.
2. Adjusting the path manually
    set path=%path%;c:\perl\bin;c:\bin
3. Call build.bat

Hacking pgbison.pl, to print PATH, shows that the path inside pgbison.pl,
returned to being the original, without the addition of c:\perl\bin;c:\bin.
my $out = $ENV{PATH};
print "Path after system call=$out\n";
Path after system
call=...C:\Users\ranier\AppData\Local\Microsoft\WindowsApps;;
The final part lacks: c:\perl\bin;c:\bin

Now I need to find out why the path is being reset, within the perl scripts.

Cause: PATH being reset.
