Others have mentioned that ANSIC is not in the implementation
reserved namespace.
I was about to say that it's redundant given the existence of
__STDC__ and __STDC_VERSION__, but if I understand your description
correctly it isn't. A fully standard conforming compiler can have
extensions; ANSIC apparently disables them, making it easier to
make sure you're writing portable code. I like the idea.
But I suggest that the name ANSIC is potentially confusing. ANSI has
not issued a C standard of its own since 1989. Instead, ANSI has
officially adopted each edition of the ISO C standard after it was
published (including the 1990 ISO C standard that superseded the
1989 ANSI C standard). Strictly speaking, the standard currently
recognized by ANSI is ISO C 2011. But for historical reasons, a lot
of people still use the term "ANSI C" to refer to the version of the
language defined by the 1989 ANSI and 1990 ISO standard documents.
And gcc's "-ansi" option still refers to the older standard; it's
equivalent to "-std=c89" or "-std=c90". (jacob, I presume you know
all this; I'm just being thorough.)
Since your ANSIC symbol specifies conformance to the C99 standard
with no extensions, I suggest calling it something like __C99_ONLY__,
or perhaps __STRICT_C99__. (The latter *might* be confused with
"strict conformance", which is a different concept.)
