Hi Josh,

I was able to reproduce this with both 32-bit and 64-bit MinGW under
MSYS2. The cause is that csc expects object files to have the .obj
extension, not a .o extension, when using MinGW. If you build fib.c
with "gcc -c fib.c -o fib.obj" and update its reference in the csc
line it will work.


Thanks,
Tim
