[dpdk-dev] [PATCH] test: fix compilation error in external memory test

[Dan Gora <dg@adax.com>]

Fix a compilation error in test_external_mem.c:

  CC test_external_mem.o
test_external_mem.c: In function ‘test_external_mem’:
test_external_mem.c:375:2: error: ‘for’ loop initial declarations are
                           only allowed in C99 mode

  for (int i = 0; i < n_pages; i++) {
  ^
test_external_mem.c:375:2: note: use option -std=c99 or -std=gnu99 to
                           compile your code
