I am trying to locate TCP_DEF_WINSIZE macro definition, but I can't find it nowhere. Did I miss something?
Look in \Keil\ARM\RV31\Inc\Net_Config.h
Oddly, Keil seem to have had a habit of removing this from one release to another. For two releases I've mentioned it to them. They have ackowledged their mistake and re-added it the subsequent release. I notice it is in the current release 4.60 and was also in 4.54. Maybe it will stick this time.

Thanks a lot!
