>Description:
The following terse (and useless) will compile and link fine,
but the executable crashes immediately:

--------------snip--------------
char mystring[]="hello";
char *end;
int main() {
  end=mystring;
  return 0;
}
--------------snip--------------

I first noticed this problem with another program
I wrote that created a pointer to a structure named "end".
I renamed it to "cend" and the program works fine now.
The Free/NetBSD versions of gcc don't have this problem.
The crash seems to occur any time you use "end" with the assignment operator.
>How-To-Repeat:
compile and attempt to run this program in a Windows environment.
>Fix:
rename any variables named "end"
