If you want build some core extensions statically into perl's dll, specify
them in the STATIC_EXT macro.
+NOTE: The USE_64_BIT_INT build option is not supported with the 32-bit
+Visual C++ 6.0 compiler.

Be sure to read the instructions near the top of the makefiles carefully.

Type "dmake" (or "nmake" if you are using that make).
This should build everything. Specifically, it will create perl.exe,
-perl515.dll at the perl toplevel, and various other extension dll's
+perl519.dll at the perl toplevel, and various other extension dll's

sure you have done the previous steps correctly.
There should be no test failures.

+Daylight Saving Time related problems: F<t/io/fs.t>,
+F<cpan/HTTP-Tiny/t/110_mirror.t> and F<lib/File.Copy.t>. The failures are

spaces. So don't do that.
