from e-support OYW-455599.
Problem was that in nctime.c#CDMonthDay, it was setting up
the month -> #days table correctly, but it did not use it
because it forgot to check for Cd366, it only checked for Cd365.
o include/nctime.h:
o Modified how the following functions are specified
external when building a DLL:
* cdRel2Iso
* cdChar2Comp
* Cdh2e
* Cde2h
* cdParseRelunits
