How to handle files with ':' in the file name?

[Peng Yu]

Hi,

I want to have filenames with ':' in Makefile. Simply adding '\'
before ':' doesn't work. I have grepped the manual by ':'. But there
are two many ':'s, I can't see where it mentiones how ':' is escaped.
Could you please let me know how to escape ':' in a Makefile?

.PHONY: all

all: a\:b.txt

a\:b.txt:
        echo $@
