From b1b952043f8f909649fdf053c371109c84f9cf56 Mon Sep 17 00:00:00 2001 From: Ramsay Jones Date: Sat, 7 Nov 2009 20:10:31 +0000 Subject: [PATCH] MSVC: Add support for building with NO_MMAP When the NO_MMAP build variable is set, the msvc linker complains: error LNK2001: unresolved external symbol _getpagesize The msvc libraries do not define the getpagesize() function, so we move the mingw_getpagesize() implementation from the conditionally built win32mmap.c file to mingw.c.
