hi, Recently, I discovered the "./configure CFLAGS=-O0" syntax: previously, I used to do "CFLAGS=-O0 ./configure" (I wonder if they are really equivalent but, this is not really my main question today). So, anyway, I use "./configure CFLAGS=-O0" and I regularly switch to "./configure CFLAGS=-O2". I would like to know if deleting config.cache is sufficient to ensure that the build is correct or if I should "make distclean" instead. A couple of tests done by building the gdb tarball appear to show that "make distclean" is the only way to ensure that the new build obeys the new flags. If so, my question is: is there a programatic way to check whether or not the flags I am asking configure to use are different from the old ones so that I can "make distclean" only when needed ?
