hadrian/make difference, you can pass --docdir, --prefix etc to initial ./configure with make (but not hadrian)
Sterni points out that with make you can run
./configure --prefix=/foo
make install
And the arguments to ./configure will also apply to the install configure script.
With hadrian the two scripts are completely separate so you have to pass --prefix=/foo
to the install configure script. There is the ./hadrian/build install --prefix=/foo
command which attempts to work around this a bit just for the --prefix
configure option but other options like --docdir
are just ignored by the initial configure script.
I think the new behaviour is right but just noting this issue in case other people run into it.
