Compiling of sortindex.c gives warnings, doesn't seem to work

[vliegelientje]

When compiling sortidx.c some warnings are being displayed.
The executable hangs, no output is displayed...

$ make
gcc -O2 sortidx.c -o sortidx
sortidx.c: In function ‘main’:
sortidx.c:69:9: warning: format ‘%d’ expects argument of type ‘int’, but argument 2 has type ‘int64_t’ [-Wformat=]
         printf("Invalid buffer size (%d).\n", bufsize);
         ^

Sorry this is shitty code. 50b0eca fixes the format string issue.

If you're sorting a big index, it will appear to hang while it's sorting (possibly for days or weeks if it's REALLY big). Giving it more memory with -r helps bring more of the sort into RAM and speeds it up a lot. If it hangs on small files that's definitely a problem.
