That's a point.

This shouldn't be a problem: just #undef it if necessary (#undef'ing at the
begin of each - automatically generated - plugin should be sufficient;
remark: so far - until your problem for *one* specific platform - there
wasn't any assert problem).

Which source code? The ST #assert: throws an exception and therefore halts
the program, what is quiet similar to my assert (I admit that the ST one is
not as radical).

I don't want to ride the horse to death (correct?). If you and others are
lucky with it, let it be #sqAssert:. But then populate please (e.g. by ST
and/or Swiki docu), that it is *forbidden* to use an assert() function like
the ST #assert: in Slang, since it would conflict with the Unix one (after C
code generation). Otherwise others could easily walk into the same trap
(mostly it would work with their platform, but not with all).

Is this a compromise?
