XFree86 doesn't use configure scripts.  I think there's some confusion
here.

1. Start with either the latest XFree86 or DRI CVS sources (at this
point, the two source bases are pretty much in sync).  Make sure
you can build and use that successfully.

2. If you want to upgrade the Mesa components within XFree86 you'll
have to get the latest Mesa sources out of Mesa's CVS tree.  Then, copy
them into the xc/extras/Mesa/src/ directory.  Specifically:
	cp Mesa-3.3/src/*.[ch] xc/extras/Mesa/src/
	cp Mesa-3.3/src/X86/*.[chS] xc/extras/Mesa/src/X86/
	cp Mesa-3.3/src/X/*.[chS] xc/extras/Mesa/src/X/

DO NOT copy the Mesa-3.3/src/FX files to xc/extras/Mesa/src/FX.

3. Recompile your XFree86/DRI tree.

Mesa itself knows absolutely nothing about the DRI or XFree86.
It's XFree86 that pulls in Mesa and hooks it into the X server and
DRI (in simple terms).
