Still an addition: Surprisingly I found in the man page of the used
"bison" release 2.7 under "Warning categories include:" the categories
'deprecated' ("obsolete constructs") and 'no-CATEGORY' ("turn off warnings
in CATEGORY") mentioned.
But manually tests with a fetched test file
bison -Wdeprecated test.y
bison -Wno-deprecated test.y
failed and issued also the mention error message.
So I downloaded and compiled bison 3.0.4 myself and the error vanishes. To
ensure it's not a problem of my openSUSE distro I downloaded and compiled
also bison 2.7 myself and I could reproduce the error. So it seems a
problem with bison 2.7 (bison 2.7.1 also issues that error, bison 3.0 not).
