c-c++-common/pr103798-2.c FAILs on Solaris when compiled as C++:
FAIL: c-c++-common/pr103798-2.c -std=gnu++14 scan-assembler-not memchr
FAIL: c-c++-common/pr103798-2.c -std=gnu++17 scan-assembler-not memchr
FAIL: c-c++-common/pr103798-2.c -std=gnu++20 scan-assembler-not memchr
FAIL: c-c++-common/pr103798-2.c -std=gnu++98 scan-assembler-not memchr
As H.J. analyzed in the PR, Solaris <string.h> declares std::memchr, not
memchr, which isn't treated as __builtin_memchr.
To avoid this, this patch declares memchr directly instead of including
<string.h>.
Tested on i386-pc-solaris2.11, sparc-sun-solaris2.11, and
i686-pc-linux-gnu.
Ok for trunk?
