/* For Solaris, Gcc automatically adds in one of the files
/usr/ccs/lib/values-Xc.o, /usr/ccs/lib/values-Xa.o, or
/usr/ccs/lib/values-Xt.o for each final link step (depending upon the other
gcc options selected, such as -traditional and -ansi). These files each
contain one (initialized) copy of a special variable called `_lib_version'.
Each one of these files has `_lib_version' initialized to a different (enum)
value. The SVR4 library routines query the value of `_lib_version' at run
to decide how they should behave. Specifically, they decide (based upon the
value of `_lib_version') if they will act in a strictly ANSI conforming
manner or not. */
