Dear Jose,
thanks, you are awesome! I was so hooked on a specific tutorial for
building MyQL-python, that I did not try anything else. With your
pointers I changed linking mysqlclient with mysql, and it links
without any trouble! No need for all the __chkstk and whatnot! So
for MinGW that seems highly prefered. I haven't tested the package
yet, keep fingers crossed :-) :-)
Thanks again and all the best,
Mario
