------- Comment #5 From Marc Peter 2006-06-25 18:03 [reply] ------- Created an attachment (id=142) [edit] updated makefiles for 1.2.11 release The new Watcom-Win32.zip - includes the new testcursor test, and - doesn't link to dxguid.lib anymore (by defining INITGUID for SDL_dx5events.c), to fix issue with stack calling convention (-6s can now be used instead of -6r in CFLAGS). ------- Comment #6 From Marc Peter 2006-06-25 18:12 [reply] ------- Created an attachment (id=143) [edit] updated README.Watcom for 1.2.11 - lists new testcursor test - mentions possibility to build with -6s (stack calling convention) instead of -6r (register calling convention)
