With binutils-2.26, gcc-5.3.0, and newlib-2.4.0:

For C99-in-C++ support, two patches are required:

iq2000-elf (PR64400), m32c-elf (PR64375), and mep-elf (PR64402) still do 
not build; the latter has been made obsolete in GCC 6.

cr16-elf and lm32-elf gcc require a patch to include newlib-stdint.h:

frv-elf gcc requires r222519:

m32r-elf gcc requires r226445:

sparc64-elf newlib sporadically fails to build:

tic6x-elf binutils requires the fix for PR gas/19614:;h=bd5608dcc6a76876db06b1af1852252a4282aa2f

v850-elf gcc requires a backport of r232451:

With the above fixes, the following targets build successfully and with 
_GLIBCXX_ENABLE_C99 (so e.g. std::to_string and std::stod are now 
available with -std=c++11):

aarch64-elf aarch64_be-elf arm-eabi bfin-elf cr16-elf cris-elf 
epiphany-elf fido-elf fr30-elf frv-elf h8300-elf i386-elf ia64-elf
