I believe that AC_TRY_COMPILE_NO_WARNING is the correct test to use
here.  We have already determined that the gethostbyname_r function
exists - we do not need to link or run a test program.  If we have
the wrong arguments to the function, we will receive a compiler 
warning and we will fail the test.  I do not see what the additional
steps of the AC_TRY_RUN test will give us.

You may be correct that the names are slightly misleading.  However,
Sterling originally intended those values to be indicative of what
the style was rather than how many arguments.  Personally, I don't
care much about names.  No one is ever happy with our names anyway.
Feel free to submit a patch that changes the #defines names if you 
want.  -- justin
