--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The problem with -fprintf-return-value is that it pretty much hardcodes the
*printf* implementation details into GCC.  And on Linux it hardcodes them for
glibc, while the kernel has its own *printf* stuff and could behave slightly
differently.
