[LTP] [PATCH v3 2/2] sigpending/rt_sigpending: add basic test

[Petr Vorel]

Hi Matthias,

> +	for (int i = 1; i < SIGMAX; ++i)
Please define i before.
Old distros using old C standards (probably -std=gnu89) by default, which breaks
build [1]:

gcc -g -O2 -g -O2 -fno-strict-aliasing -pipe -Wall -W -Wold-style-definition -D_FORTIFY_SOURCE=2 -DTEST_RT_SIGPENDING -I../../../../include -I../../../../include -I../../../../include/old/   -L../../../../lib  /usr/src/ltp/testcases/kernel/syscalls/rt_sigpending/../sigpending/sigpending02.c   -lltp -o rt_sigpending02
/usr/src/ltp/testcases/kernel/syscalls/rt_sigpending/../sigpending/sigpending02.c: In function 'test_sigpending':
/usr/src/ltp/testcases/kernel/syscalls/rt_sigpending/../sigpending/sigpending02.c:67:2: error: 'for' loop initial declarations are only allowed in C99 or C11 mode

Kind regards,
