Thanks for writing.  Who is setting _pkg_config to 'pkg-config
--static', what are they trying to do, and can it be done another way?

This doesn't look like a dash-specific phenomenon.  I get the same
result with

	$ "pkg-config --static" foo bar
	dash: 1: pkg-config --static: not found

which looks right to me.  (You can test with 'CONFIG_SHELL=/bin/ksh
ksh ./configure'.)

"dash -o debug" after a compile with DEBUG enabled.  Though "dash -x"
tends to be more helpful if you are debugging a shell script rather
than trying to find a bug in dash itself.

Hope that helps,
Jonathan
