Problem solved. :-)I found that it was @4 suffix that was missing. With a libmysql.def file as below:
LIBRARY libmysql
EXETYPE NT
SUBSYSTEM WINDOWS
EXPORTS
_mysql_init@4 = mysql_init
I was able to generate working libmysql.lib file with implib
(with /system switch).
That, with changing from extern (C) to extern (System), removed the problematic issue.
Thank you for all your hints!
