Subject: [Bug preprocessor/64220] gcc preprocessor defines outside of the reserved namespace: unix linux AVR
Date: Tue, 09 Dec 2014 01:30:00 -0000	[thread overview]
Message-ID: <bug-64220-4-iYS29Mz3Na@http.gcc.gnu.org/bugzilla/> (raw)

> Macros.html#System-specific-Predefined-Macros

When the -ansi option, or any -std option that requests strict conformance, is
given to the compiler, all the system-specific predefined macros outside the
reserved namespace are suppressed. The parallel macros, inside the reserved
namespace, remain defined.
