The C compiler supports the latest ISO C 1999
(International Standard ISO/IEC 9899:1999) standard.
With representation from IBM′s compiler development
team on the ISO/ANSI C committee, IBM is in a position
to understand the latest updates and clarifications to the
C standards. One of the benefits of conformance to
language standards is that it emphasizes the maximum
portability among a variety of compiler implementations
that also support the standard.
You can now take advantage of the IBM compiler
optimization technology that is contained in XL C/C++
Advanced Edition V6.0 for Mac OS X. You have the
flexibility to choose from various levels and types of
optimization to obtain moderate to significant
performance improvements with relatively little
development effort.
XL C/C++ Advanced Edition V6.0 for Mac OS X brings
with it IBM service and support. The IBM Service and
Support organization is made up of teams of individuals
working together to provide you with the responsive
platform and cross-platform software support that you
require. For complex or code-related problems, IBM has
specialized, skilled service teams with access to the
experts in our development laboratories, as required.
Therefore, you have access to the right level of IBM
expertise when you need it — no matter where they are
located. The vision of IBM Service and Support is to
achieve a level of support excellence that exceeds
customer expectations and differentiates IBM in the
marketplace.
