Subject[PATCH 2/7] Compiler Attributes: use the no-underscores syntax
Date
The attribute syntax optionally allows to surround attribute names
with "__" in order to avoid collisions with macros of the same name
(see https://gcc.gnu.org/onlinedocs/gcc/Attribute-Syntax.html).

This homogenizes all attributes to use the syntax without underscores.
