Yes, gcc 4.8 fails to build without this:
transport.c:1234:4: error: ‘for’ loop initial declarations are only allowed in C99 mode
for (struct ref *it = remote_refs; it; it = it->next)
^
transport.c:1234:4: note: use option -std=c99 or -std=gnu99 to compile your code
Arguably it would be nice to use -std=gnu99 for better consistency
between gcc versions, but it's moot here: avoiding the declaration in
for loop initializer is more consistent with
-Wdeclaration-after-statement anyway.
