ABOUT This folder contains helper files to build DRLVM with Microsoft Visual Studio 2003 In this version some DRLVM MSVC subprojects (both release & debug configurations) use external headers and libraries from: drlvm/trunk/build/win_ia32_msvc_debug folder (apr.h ...). So you have to build DRLVM using standard way (build update/build), before you can use MSVC build today.
