Simple Answer: Yes.
Complex Answer:
AIXv3 will, as (the currently planned, I've been away for three months)
default, provide an SysV.2/BSD4.3 namespace in its libc and include files.
By use of Feature Test Macros (compiler flags, -D) one can restrict the
namespace to XPG3, POSIX, or ANSI levels (progressively more restrictive).
The compiler will as (currently planned) default accept BOTH 'Classic' and
'ANSI' constructs, working in a 'Classic' manner. A flag will convert it
to ANSI C mode. This flag is SEPARATE from the namespace flags listed
above.
AIXv1, AIXv2, and the PS/2 version of AIXv2: No, sorry, they came out before
the standards did.
