[libcxx-commits] [PATCH] D94569: [libcxx] Wipe some more macros that do not belong in C++ forwarding headers

[Marshall Clow via Phabricator via libcxx-commits]

mclow.lists added a comment.

The C11 standard states (in section 7.21.7.5 The getc function):

2 The getc function is equivalent to fgetc, except that if it is implemented as a macro, it may evaluate stream more than once, so the argument should never be an expression with side effects.
