As requested by Adhemerval, this patch removes some preprocessor conditionals from the libio headers that were only relevant when building libio outside glibc. * libio/iolibio.h, libio/libioP.h: Remove extern "C". * libio/libio.h: Remove __BEGIN_DECLS and __END_DECLS. Remove preprocessor conditionals on _LIBC and __USE_GNU, which are always true, and __cplusplus, which is always false. --- libio/iolibio.h | 8 -------- libio/libio.h | 32 +++++--------------------------- libio/libioP.h | 8 -------- 3 files changed, 5 insertions(+), 43 deletions(-)
