pcr_tss.c: In function 'pcr_selections_match':
pcr_tss.c:73:2: error: 'for' loop initial declarations are only allowed in C99 mode
  for (int i = 0; i < a->count; i++) {
  ^
pcr_tss.c:73:2: note: use option -std=c99 or -std=gnu99 to compile your code
pcr_tss.c:78:3: error: 'for' loop initial declarations are only allowed in C99 mode
   for (int j = 0; j < a->pcrSelections[i].sizeofSelect; j++) {
   ^

Fixes: 03f99ea ("ima-evm-utils: Add support for Intel TSS2 for PCR
reading")
