So is this a C program, or C++.  This is important to know because
what you are trying to do is legal in C but not legal in C++.

i=realloc(i, 100);

Rather than trawl through your code and fixup all these problems, you
could compile with the -fpermissive switch, then gcc should behave
much like it used to.

The error message says it all.  You cannot implicitly cast the void
ptr return from malloc() to a int ptr.  If this is a C++ program you
should use new/delete rather than malloc()/free().  If this is a C
program we need to see the command line you used to compile to tell
why it is being compiled as C++ code.

DJGPP *does* work.  The problems you have are due to the fact that gcc
conforms to ANSI/ISO standard, whereas your old game project does not.
