If you look at the generated O.darwin-x86/irmSup.db.d file when that happens 
you'll see where the "}" target name is coming from, so the bug exists in our 
script that generates the dependency data.

The best solution is to put single- or double-quotes around the filenames 
inside your .substitutions file:

  file "irmPerIRM.template" {
    ...
  }

In general I would recommend doing that anyhow, bareword strings have 
character limitations.

Oops, my bad — apparently I rewrote the makeDbDepends.pl script back in June 
to /allow/ the use of quotes around filenames inside a .substitutions file.  
The previous version didn't accept them at all, and also required the '{' to 
appear on the same line as the filename, so neither of our workarounds is 
backwards-compatible.

As long as we don't want to allow filenames to contain spaces, this solves 
that problem and one other possible issue:

I've added that fix to the Known Problems page and committed it to the 3.14 
branch.
