data model.

Changes for August 2010 (429301-015)

• Added information about support for the c99 standard and the c99 compiler utility in several

chapters. For more information about this support, see “c99 Full Support” (page 461).

• Added information about the NonStop Development Environment for Eclipse (NSDEE) to

several chapters.

• Changed the usage guidelines for “NOEXCEPTIONS” (page 221) to state that the

NOEXCEPTIONS directive affects only native C++ programs compiled with the VERSION2

or VERSION3 dialects. The directive is ignored for C programs and C++ programs compiled

using VERSION1."

• Corrected all instances of the values of the -Wtarget flag to be lower case only.

• In “Installation Notes for VERSION2” (page 84), changed the text to indicate that you do not

use the RWname header files for TNS/E-targeted compilations.

• Changed the usage guidelines for “SYSTYPE” (page 250)to state that the SYSTYPE pragma

has no meaning for a DLL.

• Changed all instances of __TANDEM_ARCH_ to _TANDEM_ARCH_

Changes for November 2008 (429301-014)

• Added the compiler pragma, MULTIBYTE_CHAR (page 218).

Changes for August 2008 (429301-013)

• Added paragraph to the FIELDALIGN Usage Guidelines (page 192):

If a template class has a non-template base class or a non-template member class with the

FIELDALIGN AUTO attribute, all the instantiations of the template class should have the same

FIELDALIGN attribute as the non-template base or member class; otherwise the compilation

of such instantiations will fail.

• Added the EXCEPTION_SAFE_SETJMP (page 186) pragma that directs the compiler to do

special processing for calls to Standard C API setjmp. This enables setjmp/longjmp to be

used with C++ exception handling. This option is valid only for TNS/R C/C++.

• Under #include Usage Guidelines (page 158) and SSV Usage Guidelines (page 245), clarified

the search orders for the compilers using the #include directive.

• Under Two Memory Models: Large and Small (page 323), added a note to indicate that the

maximum code space for TNS/R and TNS/E code (irrespective of language) is 256MB, from
