make error on centos

[loveshell]

在ubuntu下没有问题，在centos下make出错

我的环境是：
os:centos 6.3
kernel:2.6.32-220.el6.x86_64
gcc version 4.4.7 20120313 (Red Hat 4.4.7-3) (GCC)

以下是我下载后的操作

Could you please try out the following commands on your side?

git reset --hard
touch src/sregex/sre_yyparser.c src/sregex/sre_yyparser.h
make

I cannot reproduce your errors on my side with bison 2.7 and 4.7.2 on Linux x86_64. And it may be an issue in your particular version of bison or gcc.

I've turned off -Werror in Makefile which should solve this issue.
