Unfortunately, I don't have such an universal CFLAGS.
With gcc-4.8 the default CFLAGS is sufficient:
$ make V=1 CC=gcc-4.8 protocol.o
gcc-4.8 -o protocol.o -c -MF ./.depend/protocol.o.d -MQ protocol.o -MMD -MP -g -O2 -Wall -I. -DHAVE_SYSINFO -DGIT_HOST_CPU="\"x86_64\"" -DHAVE_ALLOCA_H -DUSE_CURL_FOR_IMAP_SEND -DSHA1_DC -DSHA1DC_NO_STANDARD_INCLUDES -DSHA1DC_INIT_SAFE_HASH_DEFAULT=0 -DSHA1DC_CUSTOM_INCLUDE_SHA1_C="\"cache.h\"" -DSHA1DC_CUSTOM_INCLUDE_UBC_CHECK_C="\"git-compat-util.h\"" -DHAVE_PATHS_H -DHAVE_DEV_TTY -DHAVE_CLOCK_GETTIME -DHAVE_CLOCK_MONOTONIC -DHAVE_GETDELIM '-DPROCFS_EXECUTABLE_PATH="/proc/self/exe"' -DFREAD_READS_DIRECTORIES -DNO_STRLCPY -DSHELL_PATH='"/bin/sh"' -DPAGER_ENV='"LESS=FRX LV=-c"' protocol.c
protocol.c: In function ‘get_client_protocol_version_advertisement’:
protocol.c:112:3: error: ‘for’ loop initial declarations are only allowed in C99 mode
for (int i = 1; i < nr_allowed_versions; i++)

I couldn't get this error with any newer GCC or Clang, and using
options like -std=c89 trigger many other errors as well, just like you
mentioned.
