No.  Exception are the "precious" variables that have been declared as
such with AC_ARG_VAR.  It was deemed infeasible to save the state of all
environment variables, for several practical reasons.

That's why, instead of
> CRITICAL_VARIABLE=ok ./configure

you are now encouraged to use
  ./configure CRITICAL_VARIABLE=ok

for variables you want saved and restored.

Cheers,
