Subject: [PATCH] src/main.c: fix build with gcc <= 4.8

Since commit 719e44277f8e89323a87219b4d4bc7abac05b051, build with
gcc <= 4.8 fails on:

main.c:186:2: error: 'for' loop initial declarations are only allowed in C99 mode
  for (size_t i = IDX_INTERACTIVE + 1; i < NR_NFT_OPTIONS; ++i)
  ^

Fixes:
