Unfortunately the problem is that make falls over when exec'ing the commandline, including of course exec'ing xargs with redirected input, or indeed echoing to a file. The xargs solution would be perfect if it was implemented within make itself. Indeed we have used a similar technique with other makes which coped with exporting large amounts to the environment but not to the commandline or file. I can't update the zip file for each out of date file as this of course changes the zipfile timestamp after the first file. Neither can I find a way of splitting the filelist within make to echo it in parts to a file. At the moment I simply ignore dependencies and simply zip up everything in the zipfile. This is not satisfactory in the medium to long term but at least I have more than I need. Although I could split into multiple targets (zip up files starting a* then b* etc) at some point I may still bust the limit, so this would not be a robust solution. Thanks anyway for taking the time to reply. Mark P.S. Did this get copied to you by cygnus or did my mail get posted on some newsgroup? -----Original Message----- From: Martyn J.

I think that xargs may be what you're after --- it's part of the standard gnuwin32 package. It takes a bundle of arguments, a command, and repeats the command on sized chunks of those arguments, e.g., twenty at a time.
