I checked debian sid, and the build succeeds there. The code is using
UINT16_MAX in the same place (tc/tc_core.c), and that file is not
including stdint.h
UINT16_MAX is only used in tc/tc_core.c:
$ grep UINT16_MAX -r .
./tc/tc_core.c: if ((sz >> s->size_log) > UINT16_MAX) {
./.pc/ftbfs.diff/tc/tc_core.c: if ((sz >> s->size_log) > UINT16_MAX) {
UINT16_MAX is only defined in stdint.h:
$ grep UINT16_MAX -r /usr/include
/usr/include/stdint.h:# define UINT16_MAX (65535)
There are no patches defining UINT16_MAX or including stdint.h in
debian/patches.
Build flags (dpkg-buildflags) in ubuntu and sid are the same.
Without digging deeper, I don't know why the build succeeds there.
