Subject: Use finite() instead of isfinite()
X-Git-Tag: 2.1.0beta3~55
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=e84d935d96d289769672a4e0d1ff6b52f52ea49c;p=postgis

Use finite() instead of isfinite()

The former is also already used under postgis/ so we already rely
on it. The latter is been reported to be unavailable on Solaris.
