This is the same as bug 3774, but for SH instead of arm.
Compiling a 'hello, world' c++ program spews errors of the sort

.../g++-v3/bits/std_cstdio.h:145: `vfscanf' not declared

unless -D_ISOC9X_SOURCE is passed to the compiler.
The fix for arm appears to have been
which predefines _GNU_SOURCE, with the comment
/* The GNU C++ standard library currently requires _GNU_SOURCE *

Looks like other architectures might need this, too.  I'm attaching a patch
for sh4.  No idea if it's actually right yet, but it seems logical.
