Thank you kindly for providing the way to actually do the documented: "You can determine if make contains support for Guile by examining the .FEATURES variable; it will contain the word guile if Guile support is available."

Unix - the documentation is excellent if you already know how to do it...

Seriously? Is it really that hard to figure out how to look at values of variables in general?
