Hello,
writing currently GNU make compatible make files for different plattforms I
also have to deal with the Cygwin naming scheme using absolute paths within
the system. The make rules and Cygwin tools handle the Cygwin drive mapping,
the probably needed DOS/Win-based tools won't. So I have defined the
following variables to deal with the situation within the rules.
To convert your own file names or directory lists just have a look at the
first variable RT and replace the $@ by your variable. The "macro" will
preserve the sequence. You may test your variables with the debug targets at
the end (e.g. make for.TEST TEST="a b c d e f").
Hope others will find this helpfull.
Greetings
Jörg
