11 CASE: 1
147 CASE: 2
88 CASE: 3
11 CASE: 4

None of my targets used __STRINGIFY(ll##x).

Note that I'm still missing (at least) the following newlib targets:

avr-elf: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64401
cr16-elf: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64424
iq2000-elf: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64400
m32c-elf: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64403
mep-elf: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64402
or1k-elf: requires GCC 5.0
xstormy16-elf: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64407

I see you mentioned m32c earlier, do you have a patch for gcc-4.9.2?
