Yeah, so the patch removes those:
jsonapi.c:2170:53: warning: cast discards ‘const’ qualifier from pointer target type [-Wcast-qual]
jsonapi.c:2171:52: warning: cast discards ‘const’ qualifier from pointer target type [-Wcast-qual]
jsonapi.c:2172:54: warning: cast discards ‘const’ qualifier from pointer target type [-Wcast-qual]
jsonapi.c:2170:53: warning: cast discards ‘const’ qualifier from pointer target type [-Wcast-qual]
jsonapi.c:2171:52: warning: cast discards ‘const’ qualifier from pointer target type [-Wcast-qual]
jsonapi.c:2172:54: warning: cast discards ‘const’ qualifier from pointer target type [-Wcast-qual]
jsonapi.c:2170:53: warning: cast discards ‘const’ qualifier from pointer target type [-Wcast-qual]
jsonapi.c:2171:52: warning: cast discards ‘const’ qualifier from pointer target type [-Wcast-qual]
jsonapi.c:2172:54: warning: cast discards ‘const’ qualifier from pointer target type [-Wcast-qual]
ginbulk.c:247:62: warning: cast discards ‘const’ qualifier from pointer target type [-Wcast-qual]
ginbulk.c:247:79: warning: cast discards ‘const’ qualifier from pointer target type [-Wcast-qual]
parser.c:265:51: warning: cast discards ‘const’ qualifier from pointer target type [-Wcast-qual]
and looks ok.
I can see a "volatile" one though:
vacuum.c:1885:46: warning: cast discards ‘volatile’ qualifier from pointer target type [-Wcast-qual]
worth to "fix" like in the attached while at it? (It's not really a fix as it
moves the warning from vacuum.c to c.h, but that's consistent with 481018f2804).
