  I've just been trying to get MinGW working
without requiring the compiler's bin directory
to be in the PATH.  It mostly works now, but
unfortunately I ran into problems with
simple_run_action.  The problem essentially is
that this rule ignores RUN_PATH, which may be
set by some toolsets (a quick grep shows borland,
cw, gcc, and intel) to indicate additional
paths that must be added to PATH when running
the executable.  In addition, I'm wondering
how this is supposed to work with a cross-compiler.
We really shouldn't be requiring cross-compilers
to have access to the target system for ordinary
builds.

In Christ,
