So strange. You know when throwing a variable into another variable and flipping a meaning fixes your script, it's a very strange language 
.
Glad you got it working though.

gl_enablepageflipping(3) Svgalib User Manual gl_enablepageflipping(3) NAME
gl_enablepageflipping - enables automatic page flipping SYNOPSIS
#include <vgagl.h> int gl_enablepageflipping(GraphicsContext *gc); DESCRIPTION
Enable page flipping or triple buffering in gl_copyscreen(3) if the physical context gc can do it. Returns 3 if triple buffering will be used, 2 for page flipping, 0 if page flipping is not possible (due to video memory/mode limitations). When pageflipping is enabled, the gl_screenoffset(3) is ignored in gl_copyscreen(3). The idea is that you draw your picture in gc and copy it to the screen by consecutive gl_copyscreen(3) calls. Each of these will choose a free buffer in the screen and adjust the display start accourdingly. The current context must by the VGA when gl_copyscreen(3) is called in this situation. SEE ALSO
