Solaris 1.x to 2.x Transition Guide

Compiler Option Differences

Table 15-1 compares the SunOS release 4.x Sun C and ANSI C compilers to the Solaris 2.6 Sun WorkShop(TM) C++ 4.2. It is provided for your information, and is not intended to describe the range of operations available in default Solaris 2.6 software.

Note -

Table 15-1 presents information based on the publicly available copies of the American National Standard for Information Systems - Programming Language XX3.159-1989, approved December 14, 1989.

Please note the following:

A "yes" in any column indicates that the option is supported by that compiler.

If the option has changed, the new option is listed.

A "no" in any column means the option is not supported by that driver

A "+" in the Sun WorkShop(TM) C++ 4.2 Solaris 2.6 column indicates an option required by SVID specifications.
