That's what I was referring to, I should have been more specific.

Crap - I should have checked my email earlier then.  I just committed some 
changes to cvs to check for naccept using autoconf.  My checks work and 
leave the Tn5250Stream structure unchanged.  But honestly, I'm fine with 
changing the structure.  My changes aren't exactly huge, so it probably 
doesn't matter which method we use.  I figured people would rather keep 
the structure intact.

What VRM are you on?  I'm on V5R3M0 and just installed gcc via the YiP 
pages.  "gcc --version" shows version 4.0.0.  While I have resolved the 
accept/naccept issue I still have the following compiler warnings and 
errors:

Do you have any of these errors?  Did you pass any options to ./configure? 
Do you have the following line in config.log or config.h:

#define malloc rpl_malloc

Maybe getpwuid() isn't working as expected?

if you want to understand why that is, there are many good books on
the design of operating systems. please pass them along to redmond
when you're done reading them :)
