HP C/iX Reference Manual
ANSI Mode
Unless you are writing code that must be recompiled on a system where
ANSI C is not available, it is recommended that you use the ANSI mode of
compilation for your new development. It is also recommended that you
use ANSI mode to recompile existing programs after making any necessary
changes.
Because an ANSI-conforming compiler is required to do more thorough error
detection and reporting than has been traditional among C compilers, you
may find that your productivity will be enhanced because more errors will
be caught at compile time. This may be especially true if you use the
major new feature, function prototypes.
