Date: Tue, 2 Mar 2004 11:34:54 +0100 From: Bartosz Fenski aka fEnIo Subject: outdated entry in INSTALL file I've just found in INSTALL file: If you are cross-compiling from Linux to Win32, you should read the file README.Win32 But you don't shipped this file with SDL. I've found in CVS logs that this file has been deleted and this information is now in FAQ.
