That definition only occurs in `dlmalloc.h`, right? I don't think other
files import that header file, so probably `dlmalloc` only gets used under
certain configure options. I wasn't able to trace through how omalloc gets
configured/built. It seems to be a value for configure:
{{{
--with-malloc=system|dlmalloc|gmalloc|pmalloc|external
}}}
(given that singular builds just fine on OSX this cannot be a real
problem)
But yes, these changes are best made with input from someone familiar with
omalloc, so hopefully Hannes can help.
