specific, respectively, to 32–bit or 64–bit processes. This
suffix also overrides any generic, non-suffixed, version of the
environment variable that might be in effect.  Note –  Prior to
the Solaris 10 release, the link-editors ignored environment
variables that were specified without a value. Therefore, in the
following example, the generic environment variable setting,
/opt/lib, would have been used to search for the dependencies of
the 32–bit application prog.  $ LD_LIBRARY_PATH=/opt/lib
LD_LIBRARY_PATH_32=  prog  With the Solaris 10 release,
environment variables specified without a value, that have a _32
or _64 suffix, are processed. These environment vari
