The Solaris documention I've seen from Oracle says the value
of DF_1_GLOBAL is unused.
What documentation defines the purpose of DF_1_GLOBAL?
If DF_1_GLOBAL is documented somewhere, and we are following established
and compatible practice through the use of RTLD_GLOBAL, then I'm happy
to support the flag.
Is adding the testcase going to require checking for the new feature
required to set DF_1_GLOBAL?
Cheers,
Carlos.
