Subject: Add float.h include to int8.c, for isnan().
X-Git-Tag: REL_11_BETA1~1079
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=8e211f5391465bddda79e17e63c79dbc8c70e6d1;p=postgresql

Add float.h include to int8.c, for isnan().

port.h redirects isnan() to _isnan() on windows, which in turn is
provided by float.h rather than math.h. Therefore include the latter
as well.

Per buildfarm.
