Fwd: Re: svgalib 1.9.23 broken here

Hello, All,

Matan sent me a patch that fixes the problem with text not clearing  
properly from the screen when one goes from one window to the next with  
1.9.23.  If you have the problem, here is what worked for me:

1.  put the patch in a file named patchvga.h [or any other name; just  
change the command line]
2.  copy lrmi.c and lrmi.h from svgalib-1.9.21 to 1.9.23 src directory
3.  patch vga.h with patch named patchvga.h that is in svgalib-1.9.23  
directory using command:  patch src/vga.h -i patchvga.h
4.  gedit vga.h and replace all [2] instances of LRMI_regs with vm86_regs.
5.  then make uninstall, make clean, make install, make demoprogs

The patch is here:
