Hmm. This is an extremely rare situation--I think this is the first time anyone has asked for it. Unfortunately I don't think this is appropriate for a new function in GNU make: it's too rarely needed and it's _very_ system specific (what would that function do on a VMS system, or an Amiga system?) In the future we will be integrating a scripting language with GNU make, to provide a much richer set of function capabilities (this is one main reason I don't want to add too many new functions). Hopefully that language will have facilities for testing this. Thanks for the request... -- ------------------------------------------------------------------------------- Paul D.
