From e4094e49c10dba19e4c2f9fa390b12473f017c42 Mon Sep 17 00:00:00 2001 From: Corinna Vinschen Date: Wed, 7 Jun 2017 11:03:16 +0200 Subject: cygwin: Fix lrint{f,l} to return a 64 bit long on x86_64 Mingw-w64 (where the code has been taken from) has 4 byte longs independently of the architecture but x86_64 Cygwin has 64 bit longs. So use fistpll instead of fistpl on x86_64 Cygwin.
