173 /* Solaris libc and libm implement multiple behaviours for various
174 interfaces that have changed over the years in different versions of the
175 C standard. The behaviour is controlled by linking corresponding
176 values-*.o objects. Each of these objects contain alternate definitions
177 of one or more variables that the libraries use to select which
178 conflicting behaviour they should exhibit. There are two sets of these
179 objects, values-X*.o and values-xpg*.o.
180
181 The values-X[ac].o objects set the variable _lib_version. The Studio C
182 compilers use values-Xc.o with either -Xc or (since Studio 12.6)
183 -pedantic to select strictly conformant ISO C behaviour, otherwise
184 values-Xa.o. Since -pedantic is a diagnostic option only in GCC, we
185 need to specifiy the -std=c* options and -std=iso9899:199409. We
186 traditionally include -ansi, which affects C and C++, and also -std=c++*
187 for consistency.
188
189 The values-xpg[46].o objects define either or both __xpg[46] variables,
190 selecting XPG4 mode (__xpg4) and conforming C99/SUSv3 behavior (__xpg6).
191
192 Since GCC 5, gcc defaults to -std=gnu11 or higher, so we link
193 values-xpg6.o to get C99 semantics. Besides, most of the runtime
194 libraries always require C99 semantics.
195
196 Since only one instance of _lib_version and __xpg[46] takes effekt (the
197 first in ld.so.1's search path), we only link the values-*.o files into
198 executable programs. */
