 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.  */
