Programming :: C Enum Not Recognized In Local Function Scope?

I've got an enum in the global scope in my file.c. If I try to reference that enum in a function, I get an error:

Code:
// declared in the public scope:
public enum AMFFlags { AMF_AMF3 = 1<<0, AMF_BIGENDIAN=1<<1,AMF_ASSOC=1<<2,AMF_POST_DECODE = 1<<3,AMF_AS_STRING_BUILDER = 1<<4, AMF_TRANSLATE_CHARSET = 1<<5,AMF_TRANSLATE_CHARSET_FAST = 1<<5|1<<6};
// the function, declared via macro:
PHP_MINIT_FUNCTION(amf)

[Code]...
