[Serusers] MAX_BRANCH > 30 possible?

[Bogdan-Andrei IANCU]

Hi Klaus,

This limitation is because, internally, TM  uses some branch bitmaps on 
int variables -> 8*sizeof(int)=32. SO, TM is not able to track more than 
30 additionally branches (branch 0 is consider to be the default one, 
when no forking is done).
So, please don't change this, otherwise TM will be broken.
