[Help-glpk] interpretation of MPS files

I have seen that  the routines to handle MPS files were re-implemented in 
version 4.38.  
According to these changes I found a different behavior in the interpretation 
of integers w/o upper bound. It seems that an integer w/o a defined upper bound 
is interpreted as a binary variable. I guess that there is a new default value 
for a missing upper bound of an integer variable ( value of 1 instead of 
infinity in the older versions). Am I right with these assumptions?
