    Possible name clash using GCC 9.1.0 between function and stuct name

    I am building an old version of GCC (4.6.4) using GCC 9.1.0.

    And, the error looks like a name clash error to me.

    I was wondering what the C standard says about structure names and function names can they be the same.

    The error does not happen with an GCC 8.?.? or it might have been GCC 7.?.?.

    I believe the tag namespace is separate, so struct cgraph_node would not conflict with a function named cgraph_node. On the other hand, perhaps it would be a better idea to use a different function name of the verb variety, like create_cgraph_node, but perhaps the gcc authors had some convention going on. If you use a typedef for the struct though, then there would be a name collision, but that should have happened in earlier versions of gcc too.
