Question about CFLAGS handling in configure.in

[Frank L. <dj...@de...>]

In configure.in of gtkpbbuttonsd (and probably the others, too, didn't
check) you use the following snippet:

CFLAGS=
dnl Use -Wall if we have gcc.
changequote(,)dnl
if test "x$GCC" = "xyes"; then
  case " $CFLAGS " in
  *[\ \ ]-Wall[\ \      ]*) ;;
  *) CFLAGS="$CFLAGS -Wall" ;;
  esac
fi
changequote([,])dnl

which is bit "suboptimal", since it deletes all previous changes
to CFLAGS, especially such given in the configure commandline or
as enviroment variables.

Is there a good reason to do this? It seems you use this only to
filter out "-g" from CFLAGS?

Gruesse,
