I'm not sure why using Cygwin's 'make' would slow things down dramatically when running from a Cygwin terminal or shell. I can see there being some overhead if that's the only Cygwin process you're running, since there would be a Cygwin initialization cost to start 'make' if there were no other Cygwin processes running at the time. I very much doubt that this would account for the dramatic slow-down you've reported. So while certainly there's an issue here, it seems like the work-around you've found is viable. And it does make more sense than mixing and matching Cygwin and Mingw. Are you able to reproduce this problem for any kind of package? It might be helpful to know that building package or tarball 'foo' demonstrates the problem. -- Larry Hall http://www.rfk.com RFK Partners, Inc. (508) 893-9779 - RFK Office 216 Dalton Rd.
