But I fixed it differently anyway, see PR 104080.

From: LiaoShihua <shihua@iscas.ac.cn> When I built riscv-gcc with newlib, it will be terminated with message "fatal error: endian.h: No such file or directory". So, fixed it in fast_float.h. libstdc++-v3\ChangeLog: * src/c++17/fast_float/fast_float.h (defined):fast_float.h will include <machine/endian.h> with using newlib --- libstdc++-v3/src/c++17/fast_float/fast_float.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
