Initial (February 2007) Release Notes, Chapter 10: “Libraries and Programming”
• Bundled C Compiler: Updated to version A.06.12 on Integrity Servers and B.11.11.16 on
PA-RISC. Highly compatible with previous versions; diagnostic messages have changed; more
erroneous and suspicious source constructs are diagnosed.
• aC++ Run Time Library: Includes the -AA -D_HP_NONSTD_FAST_IOSTREAM performance
improvement macro, C++ Standard Library TC1 compliance change, and USA 2007 Daylight
Savings Time legislation support.
• FirstBoot: As part of Transition links (a.k.a. Upgrade), HP used to create a symbolic link
/etc/set_parms —> /sbin/set_parms. Transition links are obsoleted in HP-UX 11i v3
and set_parms is available to the user as /sbin/set_parms. So HP-UX 11i v3 will not
support the symbolic link /etc/set_parms.
• HP MLIB: Updated to version 9.5 with the addition of two new libraries, VECLIBSC8 and
LAPACKSC8, which are 64-bit address libraries with 64-bit integer values that use calling
conventions similar to those found in Cray’s SCILIB math library.
