The problem can be reproduced with this snippet:
============================= foo.c =========================
#include <stddef.h>
struct bin_str
{
size_t len; /* Number of bytes */
char const *string; /* Pointer to the same */
};
struct bin_str color_indicator[] =
{
{ 2, (char const []) {'\033','['} },/* lc: Left of color sequence */
{ 1, (char const []) {'m'} }, /* rc: Right of color sequence */
{ 0, NULL } /* ec: End color (replaces lc+rs+rc) */
};
=============================================================
$ xlc -S foo.c
"foo.c", line 9.27: 1506-196 (W) Initialization between types "const char*" and
"int" is not allowed.
"foo.c", line 9.34: 1506-026 (S) Number of initializers cannot be greater than
the number of aggregate members.
"foo.c", line 10.27: 1506-196 (W) Initialization between types "const char*"
and "int" is not allowed.
No -langlvl=... option helps.
It does not seem to be a question of C99 vs. C11, since gcc supports
this source file even with -std=c89. Rather, it appears to be a specific
xlc bug.
I propose to ignore it, because
- AIX 7.1 is end-of-life since 2023-07-28,
- Newer AIX releases come with newer compilers.
