I'm working on an autoconf test for that now.

Grr...  rpl_malloc?  That isn't even in the code!  And a quick check for 
'man rpl_malloc' on the only solaris box I have access to turns up 
nothing.  Unfortunately, I can't compile anything on it :(

But it looks like debug.c is missing stdlib.h so maybe that explains it. 
As well, config.h contains a reference to rpl_malloc that occurs when for 
whatever reason autoconf thinks that we should be using a different 
function for malloc.  The odd part is that malloc is used in other places 
but doesn't seem to be replaced with rpl_malloc.

Further review reveals that this is being done by autoconf.  But why is 
malloc being #defined to rpl_malloc in debug.c but not elsewhere?

Anyway, I've added stdlib.h to debug.c.  I can't see any reason why 
rpl_malloc is being used, but maybe this will fix it.  Plus, I've added a 
check to ./configure that should find it -lresolv is needed and add it for 
you.  I can't test any of this on solaris though :(  Would you mind 
grabbing the tarball again and giving it another shot?

If configure adds -lresolv to the linked libraries correctly then I can 
patch tn5250 to do it as well.
