Try removing the pragma; doesn't look like it's supported yet in Mesa.

    tf at tomasu dev grep -i pragma mesa/src/mesa/shader/slang/*.c
    mesa/src/mesa/shader/slang/slang_preprocess.c:#define TOKEN_PRAGMA    8

vs. `if', which seems to have an implementation:

    tf at tomasu dev grep -i token_if mesa/src/mesa/shader/slang/*.c
    mesa/src/mesa/shader/slang/slang_preprocess.c:#define TOKEN_IF        3
    mesa/src/mesa/shader/slang/slang_preprocess.c:         case TOKEN_IF:

Just a guess.
