Subject: Add missing float.h include to snprintf.c.
X-Git-Tag: REL9_0_20~66
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=00331a0f23f25944d495260796c29778649a5041;p=postgresql

Add missing float.h include to snprintf.c.

On windows _isnan() (which isnan() is redirected to in port/win32.h)
is declared in float.h, not math.h.

Per buildfarm animal currawong.

Backpatch to all supported branches.
