Subject: [PATCH] src/schedule.c: fix build with gcc 4.8

Fix the following build failure with gcc 4.8:

schedule.c:19:2: error: 'for' loop initial declarations are only allowed in C99 mode
  for (int i = 0; i < 4; ++i) {
  ^
schedule.c:19:2: note: use option -std=c99 or -std=gnu99 to compile your code
schedule.c: In function 'pms2_read_block':
schedule.c:39:2: error: 'for' loop initial declarations are only allowed in C99 mode
  for (int i = 0; i < 4; ++i) {
  ^
