You keep saying that, but that doesn't make it more right.

Thanks for posting these references in the other mail:

They are due to the Autoconf-2.59 bug in AC_CONFIG_SUBDIRS that I
mentioned earlier.  They can be reproduced with

..../newlib/configure -C CFLAGS='  -Dfoo  -Dbar  ' --target=m68k-elf 
--host=m68k-elf

And they go away if I rebuild, with Autoconf-2.60, newlib/configure and
all other configure scripts that themselves call AC_CONFIG_SUBDIRS.

So there is no need to fix CVS Autoconf to make it less sensitive to
whitespace changes: it does not have this behavior anyway.

Should I hack up a patch that fixes things for you for 2.59 only?

Cheers,
Ralf
