Add @CFLAGS@, @CPPFLAGS@, and @LDFLAGS@ in
your Makefile.in files, so they can take advantage of the values
of those variables in the environment when configure is run.
Doing this isn't necessary, but it's a convenience for users.
Also add @configure_input@ in a comment to each input file for
AC_OUTPUT, so that the output files will contain a comment saying
they were produced by configure. Automatically selecting the
right comment syntax for all the kinds of files that people call
AC_OUTPUT on became too much work.
Add config.log and config.cache to the list of files you
remove in distclean targets.
If you have the following in Makefile.in:
prefix = /usr/local exec_prefix = $(prefix)
you must change it to:
prefix = @prefix@ exec_prefix = @exec_prefix@
The old behavior of replacing those variables without @
characters around them has been removed.
