Currently, there's no _fsopen in DJGPP's libc.  To get the same
functionality, use `open' with the sharing bits you want, then call
`fdopen' to get a FILE *.  For example (UNTESTED!):

	 #include <stdio.h>
	 #include <fcntl.h>
	 ...
	 int fd = open ("foo", O_WRONLY | O_BINARY | SH_DENYWR, 0666);
	 FILE *fp = fd < 0 ? NULL : fdopen (fd, "wb");
