commit d25f0a42e822813b385f22c8a376e54833116d5a
Author: Daniel Gustafsson <address@hidden>
AuthorDate: Mon Apr 23 22:29:06 2018 +0200

    os400.c: fix ASSIGNWITHINCONDITION checksrc warnings
    
    All occurrences of assignment within conditional expression in
    os400sys.c rewritten into two steps: first assignment and then the check
    on the success of the assignment. Also adjust related incorrect brace
    positions to match project indentation style.
    
    This was spurred by seeing "if((inp = input_token))", but while in there
    all warnings were fixed.
    
    There should be no functional change from these changes.
    
    Closes #2525
