Tim Allen 5da4532771 Update to v106r55 release.
byuu says:

Everything *should* be working again, but of course that won't
actually be the case. Here's where things stand:

  - bsnes, higan, icarus, and genius compile and run fine on FreeBSD
    with GTK
  - ruby video and audio drivers are untested on Windows, macOS, and
    Linux
  - hiro is untested on macOS
  - bsnes' status bar is not showing up properly with hiro/qt
  - bsnes and higan's about screen is not showing up properly with
    hiro/qt (1x1 window size)
  - bsnes on Windows crashes often when saving states, and I'm not sure
    why ... it happens inside Encode::RLE
  - bsnes on Windows crashes with ruby.input.windows (unsure why)
  - bsnes on Windows fails to show the verified emblem on the status bar
    properly
  - hiro on Windows flickers when changing tabs

To build the Windows bsnes and higan ports, use

    ruby="video.gdi audio.directsound"

Compilation error logs for Linux will help me fix the inevitable list of
typos there. I can fix the typos on other platforms, I just haven't
gotten to it yet.
