Add a small table of integers instead as this is simpler and
avoid rounding issues (though such rounding issues are unlikely in this case)

Fixes CVE-2012-2792

Do not build from scratch the section header for each section, but build
it using the previous level buffer, thus improving efficiency.

Also fix some few corner cases related to numbering which are exposed by
the pending disposition patch.

Regular section fields nested in a regular section are now prefixed by
the nested section name.

This is required by the pending change related to disposition.

The use of the macro makes to add new optional fields somewhat harder.

patching the MinGW runtimes in newer versions. Furthermore, we now support
build with MSVC, so this section is rendered useless.
