i've now tried to compile the print_holidays example: this is what i got:

i've also tried to compile some other examples - they work, like the 
rest of my program; maybe there is something wrong with my installation 
- but i don't know what. it is also really strange that mingw accepts 
partial_date [in my app] which is derived from year_based_generator but 
refuses to work with year_based_generator*.
