Fixed bug #855 Ludwig Nussel 2009-10-18 06:31:52 PDT an mprotect call was added to fix bug 528. However that results in a buffer that allows writing and code execution. Ie the no-execute security features of modern operating systems are defeated this way. Two mprotect calls are needed. One to make the buffer executable but not writeable when done and another one to make the buffer writeable again if the content needs to be changed.

The AmigaOS code has been removed from SDL, since it had been broken for a
 long time and had a few bits of fairly invasive code #ifdef'd into the
 SDL core.

However, there is an OS4 version of SDL here:

And a MorphOS version here:
