Subject: Remove definition and usage of _hdr_math in sfio
X-Git-Tag: 2.42.0~213^2~2^2~13
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=4333ec9438e5f39187b290a84d2e9916a9290fb4;p=graphviz

Remove definition and usage of _hdr_math in sfio

The header <math.h> is not required to build lib/sfio, so the check and
the usage can be removed.
