[PATCH] D158709: [Headers][Modules] Make separate headers for the stdarg.h and stddef.h pieces so that they can be modularized

[Ian Anderson via Phabricator via llvm-commits]

iana updated this revision to Diff 553677.
iana added a comment.

Modules don't support the #include #undef #include pattern to redefine macros, the second include has no effect. Move the #undef of NULL into __stddef_null.h so that the textual behavior is preserved, but the module behavior doesn't leave NULL undefined.
