From 99d1f2c5dc02dbeac42b4d27e4798774133c618a Mon Sep 17 00:00:00 2001 From: nagachika Date: Sat, 18 Aug 2018 04:18:32 +0000 Subject: merge revision(s) 63571,63572: [Backport #14816] `int isnan(double)` is a POSIXism - `isnan` is something relatively new. We need to provide one for those systems without it. However: - X/Open defines `int isnan(double)`. Note the `int`. - C99 defines `isnan(x)` to be a macro. - C++11 nukes them all, undefines all the "masking macro"s, and defines its own `bool isnan(double)`. Note the `bool`. - In C++, `int isnan(double)` and `bool isnan(double)` are incompatible. - So the mess.
