It's displayed by ./config.status --version. E.g.,
~/build/gmp$ ./config.status --version
GNU MP config.status 6.0.0
configured by /home/nisse/hack/gmp/configure, generated by GNU Autoconf 2.69,
with options "'--disable-shared' '--disable-assembly' '--enable-assert'"

I often do that too.
With autoconf, I'd run ./config.status --version, copy and paste the
command line it displays, and edit as needed. Or more precisely, I'd
stick a "make distclean &&" before the configure command, and often "&&
make && make check" after. (Note that make distclean deletes
config.status, so things have to be done in the right order).
