Thanks, Henrik! Here are some comments on your document:
Does not mention the status of the CFE on MinGW.

If something is a list, use the HTML <ol> or <ul> tags and make it into
a real list. Otherwise, it needs to be written as prose (i.e.,
paragraphs with full sentences). In particular:

This is a list of things to do. They need to be in an HTML list.
Perhaps that whole section needs to be a list, as they are all "required

"make install" is the proper way of doing this, does this not work on

Why CFLAGS=-O? Why not -O2? Can the other flags be combined like this:
LIBCFLAGS+="-O2 -g" LIBCXXFLAGS+="-O2 -g" for brevity?

Same issue as above.

This is not changed from the standard Getting Started guide, as I
understand it, except for the two sentences in bold:
"Note: while you cannot do this step on Windows, you can do it on a Unix
system and transfer hello.bc to Windows."
"Not currently possible, but eventually will use NASMW."
As such, one cannot really "get started" using ONLY MinGW as their
platform, so this entire section should be replaced with a paragraph to
that effect, pointing the reader to the standard Getting Started guide
for more info.
