Subject: Add missing float.h include to snprintf.c.
X-Git-Tag: REL9_2_11~82
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=eae798ae1d98f8f62cc0b93a2c6972985f070446;p=thirdparty%2Fpostgresql.git

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.
