HP aC++/HP ANSI C Release Notes (B3901-90037; A.06.26; September 2011)

C++ Standard library change
Technical Corrigenda 1 has changed the STL function make_pair to take their arguments
by value instead of const reference. This change brings the HP library into compliance
if the enabling macro -D__HP_TC1_MAKE_PAIR is specified at compile time. For binary
compatibility reasons, the default behavior is unchanged.
