Hrmm. I did not think about the enum. So we have two possibilities:
1) Have some preprocessing which provides the info for the assembler
2) Use a constant for the number of PMDs which is defined in a header and
then compile time checked against the size of the fixmap in a C-file.
#1 would be preferred, but for a quick fix #2 is okay as well.
