  5. [PATCH 0/13] Add musl support to GCC
  6. 2015-05-08 Szabolcs Nagy <szabolcs.nagy@arm.com>
  7. * config/glibc-stdint.h (OPTION_MUSL): Define.
  8. (INT_FAST16_TYPE, INT_FAST32_TYPE, UINT_FAST16_TYPE, UINT_FAST32_TYPE):
  9. Change the definition based on OPTION_MUSL for 64 bit targets.
  10. * config/linux.h (OPTION_MUSL): Redefine.
  11. * config/alpha/linux.h (OPTION_MUSL): Redefine.
  12. * config/rs6000/linux.h (OPTION_MUSL): Redefine.
  13. * config/rs6000/linux64.h (OPTION_MUSL): Redefine.
