	The configure & make steps are similar to those in autogen.sh:

$ nl -ba autogen.sh 
...
     7	./configure &&
     8	rm -rf autom4te.cache &&
     9	rm -f scheme48.image build/initial.image-32 build/initial.image-64 c/scheme48.h &&
    10	make build/filenames.make &&
    11	make i-know-what-i-am-doing &&
    12	make c/scheme48.h &&
    13	make build/initial.image-32 build/initial.image-64 &&
    14	make distclean
$ 

	The only notable difference is the use of the separate build
	directory (+build-1), and it's what I'm accustomed to do
	whenever possible.

	The use of autogen.sh leads to the same result:

scheme48-4f2030ac3336 $ LC_ALL=C nohup time bash autogen.sh 
nohup: appending output to `nohup.out'
scheme48-4f2030ac3336 $ tail -n 32 nohup.out
