Ok for trunk?

As the tests assume that fileno() is visible (only part of POSIX),
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/fileno-1.c, -std=c++98
.../fileno-1.c: In function 'int test_pass_through(FILE*)':
.../fileno-1.c:5:10: error: 'fileno' was not declared in this scope
FAIL: c-c++-common/analyzer/fileno-1.c -std=c++98 (test for excess errors)
Patch has been verified on Linux.
