Subject: riscv fenv.h header file guard typo

Hi

While working on the proposed fenv.h infrastructure support, I noticed that
the riscv fenv.h and sys/fenv.h appear to have very similar header guards
(only a trailing _ differentiates them).

/libc/machine/riscv/include/fenv.h:#ifndef _FENV_H
./libc/machine/riscv/sys/fenv.h:#ifndef _FENV_H_

Would it be better for sys/fenv.h to have _SYS_FENV_H?

Yes, better.
