Date: Sun, 07 Mar 2004 22:54:11 +0900 From: Hayashi Naoyuki Subject: Tru64 cdrom and pthread option fix SDL-1.2.7/src/cdrom/osf/SDL_syscdrom.c Fixes Some CD-ROM drives(ex. TEAC CD-532E) cannot play first 150 frames(aka gap). CheckDrive() fix. The end of comment is "* /" in AddDrive(). SDL-1.2.7/configure.in Fixes Add *-*-osf pthread option and delete line SDL_LIBS="$SDL_LIBS -lrt".
