Thanks for your report, this is a bug in the kernel userspace headers.
I've attached the fix that was applied upstream.

commit 7b5b74efcca00f15c2aec1dc7175bfe34b6ec643

Revert "include/uapi/linux/atm_zatm.h: include linux/time.h"
This reverts commit cf00713a655d ("include/uapi/linux/atm_zatm.h: include
linux/time.h").
This attempted to fix userspace breakage that no longer existed when
the patch was merged. Almost one year earlier, commit 70ba07b675b5
("atm: remove 'struct zatm_t_hist'") deleted the struct in question.
After this patch was merged, we now have to deal with people being
unable to include this header in conjunction with standard C library
headers like stdlib.h (which linux-atm does). Example breakage:
x86_64-pc-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I../.. -I./../q2931 -I./../saal \
-I. -DCPPFLAGS_TEST -I../../src/include -O2 -march=native -pipe -g \
-frecord-gcc-switches -freport-bug -Wimplicit-function-declaration \
-Wnonnull -Wstrict-aliasing -Wparentheses -Warray-bounds \
-Wfree-nonheap-object -Wreturn-local-addr -fno-strict-aliasing -Wall \
-Wshadow -Wpointer-arith -Wwrite-strings -Wstrict-prototypes -c zntune.c
