+Subject: glsl: Don't inline function prototypes.
+
+Currently, the standalone compiler tries to do function inlining before
+linking shaders (including linking against the built-in functions).
+This resulted in the built-in function _prototypes_ being inlined rather
+than the actual function definition.
+
+This is only known to fix a bug in the standalone compiler; most
+programs should be unaffected.  Still, it seems like a good idea.
+
+NOTE: This is a candidate for the 7.9 branch.
