For example, I would call filtered_string=$(call my-subst,1 2 3 4 5,0123456789ABCDEFG) would produce at the end 06789ABCDEFG. It's a dummy example where I'm seeing if I can use eval to store state within a foreach construct. I would like to implement toupper and tolower using just make and compare the performance (currently I use sed, but I'd like to avoid incursions into the shell as much as I can after seeing the performance comparison of subst with $(shell ...) calls from the O'Reilly book). I also have some other character specific filtering to workaround some problem characters. I'd like to build a foreach version of the multi-character subst using eval and temp variables instead of nested $(subst ...) calls if possible. I use mingw32-make3.80, so I seem to be having problems using eval, or I don't know how to use it.
