ok, this was the problem:
the math definition files are read and then the column width is
calculated which is used in a second read
as the files to be used now have the mkii suffix, no file is read and we
end up with 24 columns which is too much for tex's calculations
I now intercept that as well as fixedthe loading (to use mkii files)
