Care to send these patches to the klibc mailing list? That way we don't
get out of sync with the next update to klibc.
thanks,

Denied. which has really bad properties on a lot of shells, and unless
you can trust "make" to invoke /usr/bin/which (or whatever it happens to
be), then you're screwed.
The reason the script invokes bash explicitly is to deal with people who
*aren't* using bash as a shell.

If people don't _have_ bash as a shell it won't work at all.
Every shell I know has ``type foo'' and return something like
``foo is /usr/bin/foo''

"something like" isn't very good. Anyway, I already reimplemented the
path search in Perl in 1.0.6, eliminating the need for the shell to do
that job.

Variations all resulted in the last argument being the full path
to the executable. And I've seen variations, so something like is
appropriate.

``#!/usr/bin/env perl'' works in most cases.
For the gcc, ld and strip you can use CC ?= cc, etc. since in that
case the path does resolve the binary name.
Indeed, that is also a solution.
Thanks for helping us poor non-bash users :-)
