most of the flags in CI are about speeding up the build and reducing
size (in particular disabling debug symbols and enabling the GS API).
Both should make no difference for the regression tests. --enable-
checking is probably worth to have.

--disable-optimising is a lie, and so is --disable-debugging. If I do:
 $ ../src/configure --disable-debugging --disable-optimising
[...]
 $ grep CXXFLAGS config.make 
CONFIG_CXXFLAGS = -g -O2  [...]

that's certainly not what I expect. The reason is that autoconf adds
default code that sets CFLAGS="-g -O2" unless the user passes a custom
value of CFLAGS. In my opinion, that contradicts the purpose of the
flags and I intend to remove them soon.

As said above, I don't think it makes a difference. If you want to, Dan
recently added "autogen.sh --ci" which gets you exactly those flags 😉
