[svn-r12110] Purpose:
Optimization
Description:
Get rid of unnecessary function call for systems that don't have rand_r.
Solution:
If rand_r isn't present on a system, then macros can be used to simply call
the underlying random function instead of calling the HDrand/HDsrand functions
that keep track of the random seed within the library.
Platforms tested:
heping (minor change)
Misc. update:
