It also allows autoreconf to work properly in the case of Autoconf and
@AUTOREMAKE@ in the case of Autosetup.
To see it, try this in the Fossil source tree to produce a debuggable build:
./configure CFLAGS='-O0 -g'
Then look at the rule generated at the end for re-generating the Makefile:
Makefile: ./Makefile.in …noise noise noise…
/path/to/configure CFLAGS=-O0
touch /path/to/Makefile
You don’t get that by exporting CFLAGS as an environment variable, for example.
