Hi.
I am checking that consider sufficient test as Marko-san and it is satisfactory.
However, That there is a portion which does not suit the solution of MSVC
also understands. Therefore, How is this proposal?
1. )remove pgevent.def
It is always generated.
2.) improvement of the Makefile and Solution.pm
What do you think?
Regards,
Hiroshi Saito
