The following dialogue in the djgpp mailing list indicates that there 
may be a bug in make.

The problem appears to arise from the fact that while there is code in
read.c, line 674 to allow a "\" to cause ":" to be read as an ordinary
character; nevertheless the code that picks up the target file (read.c
line 1521 ff.) uses savestring(), which doesn't understand "\"s.

It's not clear to me what to do without the risk of creating other bugs.

Many Thanks:

Eric Backus replies:
>>For GNU make, you can escape the ':' with a leading backslash.
