The same macro can be found in core-spa.tex, so your version of 
\dodosetupwhitespace is obsolete now. I haven't compared it to the last 
bit, but it should be the same. Time for you to clean up your sources too ;)

Best Wishes, Peter

In the core, the
   \newif \witruimteflexibel
became
   \newconditional \flexiblewhitespace

so the get the same effect as the old \witruimteflexibelfalse
and \ifwit... you now need \setfalse\flexiblewhitespace and
\ifconditional\flexiblewhitespace.

As Peter said: see core-spa.tex for details

Best wishes,
Taco

PS Hans, the \newconditional itself is actually not there. Wouldn't
   it be nicer to add it? It would help while grepping through the
   source.

Interesting lecture ... just, why does the file read:  file=core-spa,  
version=1997.03.31 ?

I hadn't expected changes by this version date.

  You shouldn't trust the version statement too much ;-)  The file itself
dates back to January 25th, and diff shows quite a lot of changes with
the version from, say, late December.
