XOR in snpsortit() of mcio.c

In this function, base[1] is assigned to 10^8, which is equal to 2, and the array base is simply (1,2,3). This causes the gcc (mine is version 13.2.1) to give the following warnings (to warn the programmer to make sure he/she doesn't accidentally use ^ to mean power instead of XOR). I noticed that this function snpsortit() is commented out, and not used any more, so it doesn't influence anything. But it might be nicer to clean it up by removing the function or change it to base[1]=2 and base[2]=3.

cc -I../include -I/usr/include/openblas -c -o mcio.o mcio.c

Open mcio.c and inspect the commented-out snpsortit() function and its base assignments. Confirm whether the function is referenced, then either remove it or replace the misleading expressions with the intended constants. Rebuild with the reported cc command and verify that the XOR-as-power warnings are gone.
