    ada: Minor cleanup in macro test
    
    The majority of the macros checked have already been checked a few line
    above. Only difference is __CYGWIN32__, so check for its absence instead
    of the presence of the others.
    
    gcc/ada/ChangeLog:
    
            * sysdep.c (getc_immediate_common): Cleanup macro test.
