According to Charles Sandmann:

I'm trying to test it but it won't compile and I can't see what the
problem is:

cc1.exe: warnings being treated as errors
malloc.c: In function `malloc':
malloc.c:238: warning: cast does not match function type
make.exe[3]: *** [malloc.o] Error 1
make.exe[2]: *** [all_subs] Error 2
make.exe[1]: *** [all] Error 2
make.exe: *** [subs] Error 2

Everything I try just makes it worse.

The patch:
