Geoff, this is caused by your patch to quote TOPLEVEL_CONFIGURE_ARGUMENTS.

First of all, you added an apostrophe at the beginning of every argument.  Did
you mean to add one at the end too?  Secondly, I'm pretty sure the arguments
aren't expanded by the shell.  I believe you took the backslash-doubling from
autoconf's handling of program_transform_name; there, the backslashes are
expanded by the surrounding backticks (echo `echo gcc | sed '$(transform)'`)
parses one more layer of backslashes than echo gcc | sed '$(transform)' does).

I've attached a patch which should fix the extra apostrophes without breaking
--program-transform-name, I'd appreciate it if you could try it.  I tested with:
 ../gcc/configure '--program-transform-name=/^[cg][^.-]*$/s/\(.*\)$/\1-3.4/'
which is really as pathalogical as you can get.  It works with bash, but not
with ash (due to a bug in autoconf!).

Reading specs from
/nevyn/big/fsf/projects/autoconf/oo/foo/bin/../lib/gcc/i686-pc-linux-gnu/3.4/specs
Configured with: ../gcc/configure
--program-transform-name=/^[cg][^.-]*$/s/\(.*\)$/\1-3.4/ --prefix=/foo
--enable-languages=c

i.e. not quoted well enough to just paste into the shell, but I think that's
OK.

Yes, I wanted to put each argument in quotes.

They are expanded once by Make, and then again by the shell inside
double-quotes.

I'm afraid I didn't get a copy of the patch, could you send it to me
privately?

I'm not sure that's quite enough of a pathological test case.  Try
adding --manpath=$(prefix)/share/man or --manpath=${prefix}/share/man ...
