/* Solaris libc and libm implement multiple behaviours for various
   interfaces that have changed over the years in different versions of the
   C standard.  The behaviour is controlled by linking corresponding
   values-*.o objects.  Each of these objects contain alternate definitions
   of one or more variables that the libraries use to select which
   conflicting behaviour they should exhibit.  There are two sets of these
   objects, values-X*.o and values-xpg*.o.

   The values-X[ac].o objects set the variable _lib_version.  The Studio C
   compilers use values-Xc.o with either -Xc or (since Studio 12.6)
   -pedantic to select strictly conformant ISO C behaviour, otherwise
   values-Xa.o.  Since -pedantic is a diagnostic option only in GCC, we
   need to specifiy the -std=c* options and -std=iso9899:199409.  We
   traditionally include -ansi, which affects C and C++, and also -std=c++*
   for consistency.

   The values-xpg[46].o objects define either or both __xpg[46] variables,
   selecting XPG4 mode (__xpg4) and conforming C99/SUSv3 behavior (__xpg6).

   Since GCC 5, gcc defaults to -std=gnu11 or higher, so we link
   values-xpg6.o to get C99 semantics.  Besides, most of the runtime
   libraries always require C99 semantics.

   Since only one instance of _lib_version and __xpg[46] takes effekt (the
   first in ld.so.1's search path), we only link the values-*.o files into
   executable programs.  */

	180	of one or more variables that the libraries use to select which
	181	conflicting behaviour they should exhibit. There are two sets of these
	182	objects, values-X.o and values-xpg.o.

	198
	199	Since only one instance of _lib_version and __xpg[46] takes effekt (the
