Subject: Remove checks standard C funcs from features/sfio
X-Git-Tag: 2.42.0~213^2~2^2~4
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=0934f47904107b65adce887b5cab4f580dfa092b;p=graphviz

Remove checks standard C funcs from features/sfio

Some functions are part of the C standard, so the checks in
features/sfio are not required and can be removed.
