Ok for trunk?
--
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.
