C++ libev-4.15没有'；t在OSX 10.8上编译

我正试图从libev-3.8（在OSX 10.8上编译得很好）升级到libev-4.15，出现以下错误

third_party/libev-4.15/ev.h:234: error: expected identifier before numeric constant
third_party/libev-4.15/ev.h:234: error: expected `}' before numeric constant
third_party/libev-4.15/ev.h:234: error: expected unqualified-id before numeric constant
third_party/libev-4.15/ev.h:842: error: expected declaration before ‘}’ token

链接到ev.h：

我的系统配置：

checking host system type... i386-apple-darwin12.3.0
checking target system type... i386-apple-darwin12.3.0
checking for ld used by gcc... /usr/llvm-gcc-4.2/libexec/gcc/i686-apple-darwin11/4.2.1/ld

FWIW，同一配置在CentOS5.6上编译得很好。

结果表明，在OSX上，“EV.h”中声明的“EV_ERROR”与“/usr/include/sys/event.h”中声明的“EV_ERROR”冲突

作为修复，我必须向前声明我使用的ev变量，而不是将ev.h直接包含在我的一个源文件中。这就成功了
