[Retroplay]

SDL2 UI fails to build on win64 (GTK3 is fine and compiles just fine with same options enabled).

MSYS2 is up-to-date as of June 22nd 2020.

For some reason the linker needed an extra flag: -lole32, which we didn't need before.

So: svn up, run ./autogen.sh, ./configure, make clean and finally make.
Hopefully it's fixed now, at least with a fully updated msys2 on a WIn7 VM I managed to build an SDL2 bindist.

svn up, run ./autogen.sh, ./configure, make clean and finally make.

Only

svn up
make

is needed -- the Makefile will do the other things.

[Retroplay]

Yup, it compiles fine again.
Thanks for the fix.

[Querino]

[gpz]
