Re: Tn5250 compile under IBM Aix 5.3

Hi again!
I've updated and configured again my PASE on the Iseries (V5R4M0) with GCC 
4.0.0 (got from Yip)
So , compiling TN5250 i am having the same problems with snprintf etc..etc.. 
as shown before from James Rich.
I will try to find GCC 4.1.1 binaries, and then i will try again to compile 
it.
There are any extra steps to follow? As i've already told it could be really 
interesting to have it working on the Iseries PASE :-)
Ciao.
ALberto.
