Visual Studio 2013 express edition does not come with the native 64bit compilers which we assume in configure. Instead it comes with a 32bit cross compilation setup. The only real difference seems to be the location of files, most notably the vcvars*.bat. Nir Lisker on build-dev has demonstrated that by changing which vcvars*.bat we look for, he was able to successfully build using express edition: http://mail.openjdk.java.net/pipermail/build-dev/2018-January/020584.html

This is what I did in toolchain_windows.m4:

    if test "x$OPENJDK_TARGET_CPU_BITS" = x32; then
       VCVARSFILE="vc/bin/vcvars32.bat"
    else
# VCVARSFILE="vc/bin/amd64/vcvars64.bat"
       VCVARSFILE="vc/bin/x86_amd64/vcvarsx86_amd64.bat"
    fi

We should update configure to at least accept this alternate path to vcvars*.bat.
