Subject: Remove checks bcopy and bzero from features/sfio
X-Git-Tag: 2.42.0~213^2~2^2~8
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=9320297db5d7cc6b6a21d9398ded931656cd603d;p=graphviz

Remove checks bcopy and bzero from features/sfio

The code contains several checks regarding these functions, but they are
never actually used in lib/sfio. It is therefore not needed to test their
availability.
