Contrary to glibc, including stdio.h from newlib defines mode_t which
conflicts with the test's type definition.
.../gcc/testsuite/gcc.dg/analyzer/fd-4.c:19:3: error: redefinition of typedef
'mode_t' with different type
...
.../include/sys/types.h:189:25: note: previous declaration of 'mode_t' with
type 'mode_t' {aka 'unsigned int'}
Defining _MODE_T_DECLARED skips the type definition.
gcc/testsuite/ChangeLog:
* gcc.dg/analyzer/fd-4.c: Fix for newlib.
---
Tested on x86_64-linux and x86_64-elf.
Ok for master?
