You attempted to hijack my simple observation ("awk is the standard name, gawk 
is not") into an attempt to replace susv3 standard utilities with extra shell 
script.  This is a separate agenda, and I have _no_ idea why you think I'm 
obligated to pursue it for you.

The motivation for my patch is taht circa 2.6.12 I didn't need gawk on my 
system to build; the need for it cropped up fairly recently.  This is A) an 
artificial requirement, B) a regression, C) trivial to fix.

I could also teach busybox awk to be called as "gawk", but awk is the standard 
name and gawk is not, and gawk can already be called as awk.  The _clean_ 
thing to do is send a patch to get Linux to use the standard name, which I 
did.  This is the minimally intrusive change, and since gawk's install 
creates an awk symlink it shouldn't affect any existing systems.

That's what I did.  I am simply not interested in your attempts to do 
something else, in hopes of fixing a problem I haven't seen and which I'm not 
convinced actually exists.

According to Posix and SUSv3, a development environment can be expected to 
have bc:

Would you like to try the one in busybox?

The minimal development environment I can build a working system in is 7 
packages: linux, gcc, binutils, make, busybox, uClibc, bash.  This is not 
theoretical: I have actually done this, and I was building systems under this 
as far back as 2003.  (I became busybox maintainer after spending 2 years 
upgrading busybox to make this _work_.  I started by rewriting sed.  I didn't 
_know_ sed at the time, but binutils ./configure used some rather advanced 
sed scripts to build, so I fixed it.  It works now.)

I'm using this to get a minimal native environment on non-x86 target 
platforms, to minimize the amount of cross compiling I have to do when 
bootstrapping a new platform.  (I submitted an OLS tutorial proposal on this, 
although I dunno if they're interested.)
