Shouldn't the manpage document that errno is undefined after a perror?

Hm, why? It will only make glibc slower and bigger.
errno value is undefined after most calls, it has defined value only when certain
functions signal an error (usually returning -1 or NULL) and only very few
functions have errno defined in all cases or unmodified.
perror is not one of them. Even if perror preserved errno value, errno is
still undefined after write or close that don't return -1.

I think it's better not to change errno rathar than modifying it.

perror is not described to set errno to any specific value, so it is allowed
to do whatever it likes with it.
