ndk And-operation between GLuint and a GLuint-type macro

Question

i encountered a problem when i try to do a and-operation between a GLuint variable and a macro which type is GLuint.

Description: The environment is jni programming on android platform I make sure i include the header paths the project needs.

in the .h file, i defined :

#define EGL_WINDOW_RGB      0;

in the .cpp file, i try to:

(flags & EGL_WINDOW_RGB)

where flags is GLuint which actually is a unsigned int type.

problem: (flags & EGL_WINDOW_RGB) get a syntax error. however, (flags & 0) is ok

Then, i want to know what's the problem
