From 0a3f4e6087e0e44fd36ca2d88f619fae2dfaa02c Mon Sep 17 00:00:00 2001 From: Corinna Vinschen Date: Tue, 20 Feb 2018 15:05:23 +0100 Subject: [PATCH] Cygwin: Make sure fraction of seconds constants enforce 64 bit computation Dropping the 'LL' specifier leads to 32 bit truncation during timestamp computation. Revert it. Exempt MSPERSEC which is used for 32 bit values.
