<pre>The GLSL spec says (emphasis mine):
"#line must have, after macro substitution, one of the following forms:
#line line
#line line source-string-number
where line and source-string-number are constant integer *expressions*."
However, Mesa's preprocessor rejects shaders like:
#line 20
#line (20)
#line (10+10)
#line +20</pre>
