commit r14-9513-g58753dba800de14144785199fd710e9b00544155 Author: Torbjörn SVENSSON <torbjorn.svens...@foss.st.com> Date: Sun Mar 10 18:18:51 2024 +0100 testsuite: Define _POSIX_C_SOURCE for test As the tests assume that strndup() is visible (only part of POSIX.1-2008) define the guard to ensure that it's visible. Currently, glibc appears to always have this defined in C++, newlib does not. Without this patch, fails like this can be seen: Testing analyzer/strndup-1.c, -std=c++98 .../strndup-1.c: In function 'void test_1(const char*)': .../strndup-1.c:11:13: error: 'strndup' was not declared in this scope; did you mean 'strncmp'? .../strndup-1.c: In function 'void test_2(const char*)': .../strndup-1.c:16:13: error: 'strndup' was not declared in this scope; did you mean 'strncmp'? .../strndup-1.c: In function 'void test_3(const char*)': .../strndup-1.c:21:13: error: 'strndup' was not declared in this scope; did you mean 'strncmp'? Patch has been verified on Linux. gcc/testsuite/ChangeLog: * c-c++-common/analyzer/strndup-1.c: Define _POSIX_C_SOURCE.
