One of the beauties of free software is that you are free to make such
changes for yourself. I don't think this is a generally useful change
though: .code16gcc is a hack to make use of gcc code in real mode where
you usually only have 64k of code space. I know it's possible to set up
16-bit segments with a larger limit, but this isn't normal.
