You can give `configure' initial values for configuration

Here
is an example:
./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
This isn't super helpful, of course, since it doesn't say exactly
which
variables any particular autoconf script responds to. But pretty much
all of the programs that a configure script searches for are reflected
as variables. A quick grep through our configure script for the
phrase
"Let the user override" finds a couple dozen hits, and that's just for
programs, never mind non-program variables.
Right, but me, while I compile lots of stuff, I don't understand
configure or autconf at all. So I was completely unaware of this
feature. I'm very pleased to know it now, of course. But I don't see
how it could be any harm to add notes to the INSTALL file explicitly
letting users know how to do stuff like this. The INSTALL file is,
after all, what folks like me read when looking for information
beyond ./configure && make && make install. It would have helped me a
lot, and I see no disadvantage to including it.
Am I missing something?
Thanks,
David
