Subject: [PATCH] Suppress -Wfloat-equal

Only NaN and Inf are not less than Inf and the check for NaN is done
before.

Solves:
.../fmt/include/fmt/format.h:2509:43: warning: comparing floating-point with '==' or '!=' is unsafe [-Wfloat-equal]
 2509 |     return !detail::isnan(value) && value != inf && value != -inf;
