Bug#950490: Acknowledgement (transition: gnat-9, Ada component of GCC-9)

[Nicolas Boulenguez]

Please ignore the two 'nw' lines and use 'nmu' instead.
nmu music123_16.4-4 .ANY . -m 'gnat (>= 9)'
nmu    topal_80-1   .ANY . -m 'gnat (>= 9)'

The paragraph explaining why ghdl is not affected also applies to
gcc-8, gcc-9 and so on.
