Hi,
why OSTYPE=windows ? I don't see a make/make.windows.x86_64.msvc.opt in
my version of SCIP.
Somehow -DNO_SIGACTION seems to be missing in the compiler flags. You
could add USRFLAGS=-DNO_SIGACTION to your call of make.

Actually, this has not much to do with MinGW. Or do you want to use MinGWs gcc compiler? Of course, this would be an alternative to MSVC.
