In the meantime I recompiled 1.1.43 with cflags=-O2 now, but it really doesn't
matter. 
Frankly, I was not quite thorough in my testing: with shadows disabled only the
opening scene is playable, entering the first tutorial mission gives a lot of
those err: ...glsl_shader.c 4572 lines for me, too, and performance dropped
significantly.
Moreover, those erroneous lines were present in 1.1.42, too.
Now I'm a bit confused: originally I only observed the huge slowdown with
shadows=normal, and that wasn't so significant in 1.1.42.
