Subject: Move FLAG_ macro from defs.h to macros.h
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=2ee949aeb234e7e0fcbed72889e253da041dd8e1;p=strace

Move FLAG_ macro from defs.h to macros.h

Rename it to FLAG and implement via newly added BIT helper macro,
in preparation for general use

* defs.h: Use FLAG instead of FLAG_.
(FLAG_): Move it...
* macros.h (FLAG): Here, implement using BIT macro.
[!BIT] (BIT): New macro.
