[m-rev.] diff: fix compilation failure

[Julien Fischer]

Zoltan, this was caused by commit #2530d0d; possibly only part of a 
change was committed / pushed?

------------------------------

Fix compilation failure.

compiler/make_hlds_passes.m:
     Undo commit #2530d0d, which fails to compile.

Julien.
