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