From 2d26512b45b5236fa521c4492608fe9fb5bedf46 Mon Sep 17 00:00:00 2001 From: Stefan Weil Date: Sat, 10 Mar 2012 21:20:53 +0100 Subject: [PATCH] slirp: Fix compiler warning for w64 Casting a pointer to an integer value must use uintptr_t or intptr_t (not long) for portable code. MinGW-w64 requires this because sizeof(long) != sizeof(void *) for w64 hosts, so casting to long raises a compiler warning. I use uintptr_t instead of intptr_t because changing the sign does not matter here and casting pointers to unsigned values seems more reasonable (the unsigned value is a non negative offset.
