When using a compiler defaulting to -std=gnu90, we run into: ... Running gdb.server/attach-flag.exp ... gdb compile failed, attach-flag.c: In function 'main': attach-flag.c:22:3: error: 'for' loop initial declarations are only allowed \ in C99 or C11 mode for (int i = 0; i < NTHREADS; i++) ^~~ attach-flag.c:22:3: note: use option -std=c99, -std=gnu99, -std=c11 or \ -std=gnu11 to compile your code ... Fix this by using -std=gnu99. Tested on x86_64-linux.
