At which point is the build failing now? It might simplify things to
copy your lisp directory from another plaform to avoid the need to
bootstrap, as that is where most subtle problems with Windows build
environments come up.
I think I have fixed the font selection problem, by adding code to copy
the entries from font_entity to the new font_object in
w32font_open_internal.
Now there is one remaining problem that I can see. When no font is found
for some characters, display on that line is corrupted. The first time
such a problem is encountered, all characters in the default face on
that line are corrupted (I think this is caused by hitting a problem
getting the glyph code, so code in w32font_encode_char decides to switch
to using Unicode output for that font from that point on, so any glyphs
that have already been encoded but not yet displayed are invalidated -
the code was designed like this because for non-truetype fonts, and on
older versions of Windows, it is not possible to get a glyph code, but I
did not expect it to fail for a font where it had previously succeeded).
After that, there is always a garbage character following the boxes that
indicate a missing font. If the cursor is anywhere on the line, then the
garbage character changes, at the same rate the cursor is blinking at.
