Fix 2001/anonymous - it now works!
This was a fun one to figure out. There were a few steps. Amongst them was adding the include for mmap(). Another part that might or might not be relevant was having main() call a new function rather than main() itself. This seemingly solved an infinite recursion call to main() (according to gcc). I changed the third arg in the call to mmap() to be PROT_READ|PROT_WRITE. This might not have been necessary as it might evaluate to 3 which is what it was. I regret that some macros were removed and some formatting was changed. This was not intentional but I want to get the fix in and then I can fix the formatting and macros (or try to - some of it might or might not cause a problem). Note that it will crash on any binary that's not 32-bit/x86. In other words this won't work in macOS unless you have an old enough Mac that supports 32-bit binaries. With gcc (which is clang in macOS so that won't work either) one can do -m32 and that's what is done for anonymous.ten. It probably should be built by default but it's currently not.
