I think for 2.60 we took care that AC_CONFIG_SUBDIRS and the like don't
munge whitespace -- that was a cause for failure.  And some more global
$as_echo changes in 2.61b (CVS).  But I guess that doesn't apply to GCC
as it calls the sub-configures manually.

In which cases do you see these, and what's the cause for the changed
white space?

Not at the moment.  I guess as a hack you could redefine the macro
_AC_ARG_VAR_VALIDATE.  You may still have to do the passing to
config.status in that case.

Hope that helps.
