I've still got the 'i686-w64-mingw32-gcc -fstack-protector-strong' executable:
C:/cygwin/home/Lee/t/div.exe: error while loading shared libraries: ?:
cannot open shared object file: No such file or directory
$ objdump -x ./div.exe | egrep -i "dll name"
DLL Name: KERNEL32.dll
DLL Name: msvcrt.dll
DLL Name: libssp-0.dll
shows libssp0 as the GCC Stack-Smashing Protection runtime library
but I don't see anything like that with a leading "mingw64-i686-"
name, so I'm out of luck?
