    Fix compilation error with clang in gdb/testsuite/gdb.trace/tspeed.c
    
    Clang fails to compile the above file, with the following error:
      warning: using the result of an assignment as a condition without
      parentheses [-Wparentheses]
    
    This prevents the following testcase from executing:
      gdb.trace/tspeed.exp
