Description Michael Darling 2015-05-20 23:08:28 UTC 
I'm using -Werror=zero-as-null-pointer-constant.

I'm using a library with a header providing default values on some functions of NULL.

gcc trunk issues an error, since I'm using that default value.

But, I included that library's headers with -isystem.

I get that in one sense NULL is "imported" into my source and used, but I really think the spirit of -isystem is being violated here.  I either have to edit library header files which aren't mine, or I can't use -Werror=zero-as-null-pointer-constant.
