Browse Source 
Fix the following build failure with gcc 4.8 raised since bump to
version 2.86 in commit 5b29096f8f:

option.c: In function 'one_opt':
option.c:2445:11: error: 'for' loop initial declarations are only allowed in C99 mode
           for (char *p = arg; *p; p++) {
           ^
option.c:2445:11: note: use option -std=c99 or -std=gnu99 to compile your code
option.c:2453:11: error: 'for' loop initial declarations are only allowed in C99 mode
           for (u8 i = 0; i < sizeof(daemon->umbrella_device); i++, arg+=2) {
           ^
