C application developers have to deal with name space conflicts SOMEhow.
You should NOT start using _names, because those are reserved for C
implementions.  You can use any names that you're sure will not be
#defined before your header is included.  What those names are depends
on the name space partitioning rules you have adopted.  If you use the
"package prefix" notion I've described in previous postings, then names
incorporating the header's package prefix would be wise.
