++4.9c-Gentoo -- Thu Jun 26 16:57:16 MDT 2008 -- Joe Peterson <joe@skyrush.com>
++
++* Patched for Gentoo ebuild
++  - Added assignment to volatile variable in the z80 delay loop
++    (allows near-actual speed emulation with optimization)
++  - Fixed keyboard wait issue that caused CPU spinning (i.e. max
++    CPU usage) after using F10 (reset), F7, F8, or F9.
++  - Disable SIGIO
++  - Added NEWDOS/80 system date/time auto-initialization
