Use ls -i to find out the inode number of the file/link and then either
use
find . -inum xxxx -exec rm '{}' \;
or the following short program to delete the file.

/*
 * remove a file at a given inode number in the current directory usage: rm
 * <inode_number> useful for getting rid of files with strange names. Safer
 * than clri and can be run without being root.
 * Very simple-minded, but useful.
 * Usage:
 *	irm <inode-number>
 * The inode number can be obtained by using ls -i
 * So to get rid of file *****.???'\^C^D^Z
 * cd into the directory containing the file.
 * Do an ls -i and find the inode number of the file 
 * (say 30240) then type
 * irm 30240

 * BSD43 is for VAX BSD 4.3 (do not use BSD43 for SUN OS 4.0+) Tested under SUN
 * OS 4.0 and VAX BSD 4.3. Is BSD43 is not specified compiles for SUN OS 4.0/4.1
