173 interfaces that have changed over the years in different versions of the
174 C standard. The behaviour is controlled by linking corresponding
175 values-*.o objects. Each of these objects contain alternate definitions
176 of one or more variables that the libraries use to select which
177 conflicting behaviour they should exhibit. There are two sets of these
178 objects, values-X*.o and values-xpg*.o.
180 The values-X[ac].o objects set the variable _lib_version. The Studio C
181 compilers use values-Xc.o with either -Xc or (since Studio 12.6)
182 -pedantic to select strictly conformant ISO C behaviour, otherwise
185 The values-xpg[46].o objects define either or both __xpg[46] variables,
186 selecting XPG4 mode (__xpg4) and conforming C99/SUSv3 behavior (__xpg6).
188 Since GCC 5, gcc defaults to -std=gnu11 or higher, so we link
189 values-xpg6.o to get C99 semantics. Besides, most of the runtime
190 libraries always require C99 semantics.
192 Since only one instance of _lib_version and __xpg[46] takes effekt (the
193 first in ld.so.1's search path), we only link the values-*.o files into
