版本：Fedora release 25 (Twenty Five)
gcc version 6.3.1 20161221 (Red Hat 6.3.1-1) (GCC)
为什么单独拿出来这个说呢？
因为从GCC 6 开始，gcc已经提供cstdlib，这时如果在再使用-isystem，就会报错
In file included from /usr/include/c++/6.3.1/ext/string_conversions.h:41:0,
from /usr/include/c++/6.3.1/bits/basic_string.h:5402,

需要修改
irstlm/src/Makefile.am
和
irstlm/src/Makefile.in
把里面的
AM_CXXFLAGS = -static -isystem/usr/include -W -Wall -ffor-scope -D_FILE_OFFSET_BITS=64 -D_LARGE_FILES $(BOOST_CPPFLAGS) -DMYCODESIZE=3
修改为：
AM_CXXFLAGS = -static -W -Wall -ffor-scope -D_FILE_OFFSET_BITS=64 -D_LARGE_FILES $(BOOST_CPPFLAGS) -DMYCODESIZE=3
这样再运行脚本 extras/install_irstlm.sh，就可以顺利编译了。
