Interesting. 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.
