libgpg-error-1.12 openwrt 编译错误

使用gcc5.3编译libgpg-error-1.12出现
gawk -f ./mkerrcodes.awk >mkerrcodes.h
rm _mkerrcodes.h
cc -I. -I. -o mkerrcodes ./mkerrcodes.c
In file included from ./mkerrcodes.c:26:0:
./mkerrcodes.h:9:5: error: expected expression before ',' token
{ , "GPG_ERR_E2BIG" },

gcc 4.8.3 编译没有问题
使用下面补丁
