  Hum, this looks sensible but the best is probably to ask the author
of the pascal wrapper.
  I remember for example (old memory from the TurboPascal at the end of
the 80's) that Pascal strings had a different in-memory representation
from C ones. For the floats, it's strange it should be mostly architecture
dependant, not language dependant...
